DESCRIPTION
The M54/74HC367 and the M54/74HC368 are high
speed CMOS HEX BUS BUFFER (3-STATE) fabri-
cated in silicon gate C²MOS technology. They have
the same high speed performance of LSTTL com-
bined 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 (HC367) and inverting outputs (HC368).
All inputs are equipped with protection circuits
against static discharge and transient excess volt-
age.
