TC4423CPA General Description

The TC4423/4424/4425 are higher output current versions of the new TC4426/4427/4428 buffer/gate drivers which, in turn, are improved versions of the earlier TC426/427/428 series. All three families are pin-compatible. The TC4423/4424/4425 gate drivers are capable of giving reliable service in far more demanding electrical environments than their antecedents. Although primarily intended for driving power MOSFETs, the TC4423/4424/4425 gate drivers are equally well-suited to driving any other load (capacitive, resistive, or inductive) which requires a low impedance driver capable of high peak currents and fast switching times. For example, heavily loaded clock lines, coaxial cables, or piezoelectric transducers can all be driven from the TC4423/4424/4425. The only known limitation on loading is the total power dissipated in the driver must be kept within the maximum power dissipation limits of the package.

In the city of dnepr the parcel reached in 19 days. The appearance of the leds corresponds to the description and photos on the site. The tape with leds is packed in a paper bag-all whole. Bought to repair the backlight of the tv, but the leds themselves have not yet checked and did not put in the tv.

As good a partner you could find.

Came quickly, alerted a couple of small things. 1. the firmware is loaded only if choose "old bootloader" in arduino ide. 2. when first connected to power, the tx led blinked, instead of the 13th led and blinked it until i poured a new sketch. 3. led power green, instead of standard red.
