The M54/74HC242/243 are high speed CMOS
QUAD BUS TRANSCEIVER (3-STATE)
FABRICATED IN SILICON GATE C2MOS
technology. They have the same high speed
performance of LSTTL combined with true CMOS
low power consumption. The HC242/243 are 3
STATE bi-directional inverting and non-inverting
buffers and are intended for two-way asynchronous
communication between data buses. They are high
drive current outputs which enable high speed
operation when driving large bus capacitances.
Each device has one active high enable (GBA), and
one active low enable (GAB). GBA enables the A
outputs and GAB enables the B outputs. 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
