Philips Semiconductors Product specification

Quad 2-input AND gate 74HC/HCT08

FEATURES

• Output capability: standard

• ICC category: SSI

GENERAL DESCRIPTION

The 74HC/HCT08 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL).
They are specified in compliance with JEDEC standard no. 7A. The 74HC/HCT08 provide the 2-input AND function.

Notes

1. C

PD

is used to determine the dynamic power dissipation (PDin µW):

PD= CPD× V

CC

2

× fi+ ∑ (CL× V

× fo) where:
fi= input frequency in MHz
fo= output frequency in MHz
CL= output load capacitance in pF
VCC= supply voltage in V
∑ (CL× V

× fo) = sum of outputs

2. For HC the condition is VI= GND to V

CC

For HCT the condition is VI= GND to VCC−1.5 V
