DESCRIPTION
The M54/74HC365 and the M54/74HC366 are high
speed CMOS HEX BUS BUFFER fabricated in sili-
con gate C2MOS technology. They have the same
high speed performance of LSTTL combined with
true CMOS low power consumption.
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 in-
puts are held low, under all other conditions these
output 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 (HC365) and inverting outputs (HC366). All
inputs are equipped with protection circuits against
static discharge and transient excess voltage.

(*) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without load.
(Refer to Test Circuit). Average operting current can be obtained by the following equation. ICC(opr) = CPD •VCC •fIN + ICC/6 (per Gate)
TEST CIRCUIT ICC (Opr.)
CPD CALCULATION
CPD is to be calculated with the following
formula by using the measured value of
ICC (opr.) in the test circuit opposite.
CPD
=
ICC (opr)
fIN × VCC
In determining the typical value of CPD a
relatvely high frequency of 1 MHz was ap-
plied to fIN, in order to eliminate any error
caused by the quiescent supply current.
INPUT WAVEFORM IS THE SAME AS THAT IN CASE OF
SWITCHING CHARACTERISTICS TEST.
