Product speciﬁcation

Hex buffer/line driver; 3-state; inverting

74HC/HCT368

FEATURES

• Inverting outputs

• Output capability: bus driver

• ICC category: MSI

GENERAL DESCRIPTION

The 74HC/HCT368 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/HCT368 are hex inverting buffer/line drivers

with 3-state outputs. The 3-state outputs (nY) are

controlled by the output enable inputs (1OE, 2OE).

A HIGH on nOE causes the outputs to assume a high

impedance OFF-state.

The “368” is identical to the “367” but has inverting outputs.

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 × VCC2 × fo) = sum of outputs

CL = output load capacitance in pF

VCC = supply voltage in V

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

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