GENERAL DESCRIPTION
74HC/HCT86
The 74HC/HCT86 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/HCT86 provide the EXCLUSIVE−OR function.

Notes to HCT types
The value of additional quiescent supply current (∆I
CC
) for a unit load of 1 is given in the family specifications.
To determine
∆I
CC
per input, multiply this value by the unit load coefficient shown in the table below.
