The TC4426A/4427A/4428A are improved versions of the earlier TC426/427/428 family of buffer/drivers (with which they are pin compatible). They will not latch up under any conditions within their power and voltage ratings. They are not subject to damage when up to 5V of noise spiking (of either polarity) occurs on the ground pin. They can accept, without damage or logic upset, up to 500mA of reverse current (of either polarity) being forced back into their outputs.

Wide Operating Range: 4.5V to 18V
High Capacitive Load Drive Capability: 1000pF in 25nsec
Short Delay Times: <30nsec Typ.
Matched Rise, Fall and Delay Times
Low Supply Current:
With Logic '1' Input: 1mA
With Logic '0' Input: 100μA
Low Output Impedance: 7Ω Typ.
Latch-Up Protected: Will Withstand >0.5A Reverse Current
Input Will Withstand Negative Inputs Up to 5V
ESD Protected: 4kV
Pinouts Same as TC426/27/28
