DESCRIPTION
The M54/74HCT367 and the M54/74HCT368 are
high speed CMOS HEX BUS BUFFER (3-STATE)
fabricated in silicon gate C
have the same high speed performance of LSTTL
combined with true CMOS low power consumption.
These devices contain six buffers, four buffers are
controlled by an enable input (G1) and the other two
buffers are controlled by the other enable input
(G2) ; the outputs of each buffer group are enabled
when G1 and/or G2 inputs are held low, and
when held high these outputs are disabled to be
high-impedance.
These outputs are capable of driving up to 15 LSTTL
loads. The designer has a choice of non-inverting
outputs (HCT367) and inverting outputs (HCT368).
All inputs are equipped with protection circuits
against static discharge and transient excess volt-
age.
This integrated circuit has input and output charac-
teristics that are fully compatible with 54/74 LSTTL
logic families. M54/74HCT devices are designed to
directly interface HSC
NMOS components. They are also plug in replace-
ments for LSTTL devices giving a reduction of
power consumption.
All inputs are equipped with protection circuits
against static discharge and transient excess volt-
age.
