Philips Semiconductors 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 (n
Y) 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.

is used to determine the dynamic power dissipation (PD in µW):
PD=CPD× V

× fo) where:
fi= input frequency in MHz
fo= output frequency in MHz

× fo) = sum of outputs
CL= output load capacitance in pF
VCC= supply voltage in V
