High Speed CMOS Logic

Quad-Bus Transceiver with Three-State Outputs

Features

Description

• Typical Propagation Delay (A to B, B to A) of 7ns at

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

= 5V, C = 15pF, T = 25 C

• Wide Operating Temperature Range . . . -55 C to 125 C

• Balanced Propagation Delay and Transition Times

The CD74HCT242 is an inverting buffer; the ’HC243 and

’HCT243 are non-inverting buffers.
