description
These hex buffers and line drivers are designed
specifically to improve both the performance and
density of 3-state memory address drivers, clock
drivers, and bus-oriented receivers and
transmitters. The ’HC365 contain six independent
buffers/drivers with dual-gated output-enable
(OE1 and OE2) inputs. When OE1 and OE2 are
both low, the device passes noninverted data from
the A inputs to the Y outputs. If either (or both)
output-enable terminal(s) is high, the outputs are
in the high-impedance state.
The SN54HC365 is characterized for operation
over the full military temperature range of –55°C
to 125°C. The SN74HC365 is characterized for
operation from –40°C to 85°C.

‡ Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
2. The package thermal impedance is calculated in accordance with JESD 51, except for through-hole packages, which use a trace
length of zero.

B. Waveform 1 is for an output with internal conditions such that the output is low except when disabled by the output control.
Waveform 2 is for an output with internal conditions such that the output is high except when disabled by the output control.
C. Phase relationships between waveforms were chosen arbitrarily. All input pulses are supplied by generators having the following
characteristics: PRR

1 MHz, ZO = 50
Ω,
tr = 6 ns, tf = 6 ns.
D. The outputs are measured one at a time with one input transition per measurement.
E. tPLH and tPHL are the same as tpd.
F. tPLZ and tPHZ are the same as tdis.
G. tPZL and tPZH are the same as ten.
