Quad 2-input NAND gate 74HC/HCT03
FEATURES
• Level shift capability
• Output capability: standard (open drain)
• ICC category: SSI
The 74HC/HCT03 provide the 2-input NAND function.
The 74HC/HCT03 have open-drain N-transistor outputs,
which are not clamped by a diode connected to V
the OFF-state, i.e. when one input is LOW, the output
may be pulled to any voltage between GND and V
This allows the device to be used as a LOW-to-HIGH or
GENERAL DESCRIPTION

and are pin compatible with low power Schottky TTL
(LSTTL). They are specified in compliance with JEDEC
standard no. 7A.
