Product speciﬁcation

Quad 2-input EXCLUSIVE-NOR gate

74HC7266

FEATURES

• Output capability: standard

• ICC category: SSI

GENERAL DESCRIPTION

The 74HC7266 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 74HC7266 provide the EXCLUSIVE-NOR function with active push-pull output.

QUICK REFERENCE DATA

GND = 0 V; Tamb =25 °C; tr =tf = 6 ns

Notes

1. CPD is used to determine the dynamic power dissipation (PD in µW):

PD =CPD × VCC2 × fi +∑ (CL × VCC2 × fo) where:

fi = input frequency in MHz

fo = output frequency in MHz

CL = output load capacitance in pF

VCC = supply voltage in V

∑ (CL × VCC2 × fo) = sum of outputs

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

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