PIN AND FUNCTION COMPATIBLE WITH
74 SERIES 365
DESCRIPTION
The 74HC365 is an advanced high-speed CMOS
HEX BUS BUFFER (3-STATE) fabricated with
silicon gate C
2
MOS technology.
All six buffers are controlled by the combination of
two enable inputs (G1 and G2); all outputs of
these buffers are enabled only when both G1 and
G2 inputs are held low, under all other conditions
these outputs are disabled in a high-impedance
state.
The M74HC365 has non inverting outputs.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
