Quad-Bus Transceiver with Three-State Outputs
Description
The CD74HCT242, ’HC243 and ’HCT243 silicon-gate
CMOS three-state bidirectional inverting and non-inverting
buffers are intended for two-way asynchronous communica-
tion between data buses. They have high drive current out-
puts which enable high-speed operation when driving large
bus capacitances. These circuits possess the low power dis-
sipation of CMOS circuits, and have speeds comparable to
low power Schottky TTL circuits. They can drive 15 LSTTL
o
o
loads.
C to 125
C
The CD74HCT242 is an inverting buffer; the ’HC243 and
’HCT243 are non-inverting buffers.
The states of the output enables (OEB, OEA) determine
both the direction of flow (A to B, B to A), and the three-state
mode.
