GENERAL DESCRIPTION
The TC4423/4424/4425 are higher output current versions of the new TC4426/4427/4428 buffer/drivers, which, in
turn, are improved versions of the earlier TC426/427/428 series. All three families are pin-compatible. The TC4423/
4424/4425 drivers are capable of giving reliable service in far more demanding electrical environments than their antecedents.
