DESCRIPTION
The M54/74HC367 and the M54/74HC368 are high
speed CMOS HEX BUS BUFFER (3-STATE) fabricated in silicon gate C2MOS technology. They 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.
HC367
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 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 Channel)
TEST CIRCUIT ICC (Opr.)
C PD CALCULATION
CPD is to be calculated with the following
formula by using the measured value of
ICC (opr.) in the test circuit opposite.
ICC ( opr)
CPD =
fIN × VCC
In determining the typical value of CPD, a
relatively high frequency of 1 MHz was applied 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.
