Description
MICROCHIP TC427CPA Dual MOSFET Driver IC, Low Side, 4.5V-18V Supply, 1.5A Out, 75ns Delay, DIP-8The TC427CPA is a 1. 5A dual high speed power MOSFET Driver for use with pulse transformer drive. TTL CMOS input voltage level is translated into a rail to rail output voltage level swing. The CMOS output is within 25mV of ground or positive supply. The low impedance, high current driver outputs swing a 1000pF load 18V in 30ns. The unique current and voltage drive qualities make the TC427 ideal power MOSFET drivers, line drivers and DC to DC converter
The TC427CPA is a 1.5A dual high-speed power MOSFET Driver for use with pulse transformer drive. TTL/CMOS input voltage level is translated into a rail-to-rail output voltage level swing. The CMOS output is within 25mV of ground or positive supply. The low-impedance, high-current driver outputs swing a 1000pF load 18V in 30ns. The unique current and voltage drive qualities make the TC427 ideal power MOSFET drivers, line drivers and DC-to- DC converter building blocks. Input logic signals may equal the power supply voltage. Input current is a low 1µA, making direct interface to CMOS/bipolar switch-mode power supply control ICs possible, as well as open-collector analog comparators. Quiescent power supply current is 8mA maximum. The TC426 requires 1/5 the current of the pin-compatible bipolar DS0026 device. This is important in DC-to-DC converter applications with power efficiency constraints and high-frequency switch-mode power supply applications.
- Single supply operation
- TTL/CMOS input compatible
- Available in non-inverting configuration
- Latch-up resistant of withstands >500mA reverse current
- 6R Low output impedance
- 1µA Low input current
- 2kV ESD protected
Applications
Power Management, Clock & Timing, Industrial
Warnings

Size: 6 Pairs - 6 Colors Assorted
Works great for myself & hub! I bought them mostly for him because his feet are wrecked, but it’s a 6 pack, so yay me. The cushiony heel was a bonus I didn’t expect, so nice + comfortable to sleep in- usually hate sleeping in socks but since your toes are free, these do not bug at all. Definitely get these

Go buy these heels socks they’re the best
Size: 6 Pairs - 6 Colors Assorted
I love that they have gel in the heels. I sleep in a pair and even wear a pair to work for extra protection for my heels. They are great to get your heels soft and prepared for the sandal wearing days of summer. They slide on my feet so comfortably because of the great stretch they have. I just love how they feel on my feet , walking in them is very easy and comfy and they don’t slide or is slippery. You can even wash them like regular socks and wear them over and over. I would recommend them to anyone who wants baby soft heels.

Love these
Size: 6 Pairs - 6 Colors Assorted
These are fantastic if you want a 'foot mask on the go'. They fit easy, the colors are great, and they work! I used them after putting on moisturizer and my heels were smooth and looked great in sandals after! No cracks or dry patches!

These really work.
Size: 6 Pairs - 6 Colors Assorted
Very pleased with these. They really work, especially if using a pumice in the morning after removing them, makes it really easy to remove dead skin. They are very soft and reasonably comfortable so it’s not an issue during sleep. Not really a fan of the rose scent but that’s not too strong and dissipates after a few days. These wash well. It would be nice if the hem seam at the front end was finished the same way as the ankle end. This is very nice and flat, the one at the front has a bit of a protruding roll. Altogether, these are worth it. They do the job, are comfortable, and a good value.

A must for dry cracked heels.
Size: 6 Pairs - 6 Colors Assorted
I have to keep on top of my feet because the bottom of my heels get really dry. I have to soak them every 2 weeks so they don't look like horse hooves. With the spring and summer coming, the feet get drier , flip flops and sandals or any shoes without shocks really make them feel worse. These REALLY help maintain my soles beautiful and cushiony. I love to be barefoot around the house and these give the the feel of barefeet and the comfort of a sock on the heel. At night i always put lotion on my feet but can't sleep with socks because i overheat, these i can put my lotion and then a little urea stick on the heel and put them on and sleep like a baby.
These need to be hanwashed and air dried to preserve the integrity of the gel on the sock. Just be aware of that. Fit wise i am a 7.5 on the wider side and these fit very well without being tight anywhere. I also put these on with flip flops and they look great and feel better too.
