MC74LCX16245
Low−Voltage CMOS
16−Bit Transceiver
With 5 V−Tolerant Inputs and Outputs
(3−State, Non−Inverting)
transceiver operating from a 2.3 to 3.6 V supply. The device is byte
controlled. Each byte has separate Output Enable inputs which can be
tied together for full 16−bit operation. High impedance TTL
compatible inputs significantly reduce current loading to input drivers
while TTL compatible outputs offer improved switching noise
performance. A V
inputs to be safely driven from 5.0 V devices. The MC74LCX16245 is
suitable for memory address driving and all TTL level bus oriented
transceiver applications.
applications. Current drive capability is 24 mA at both A and B ports.
The Transmit/Receive (T/Rn) inputs determine the direction of data
flow through the bidirectional transceiver. Transmit (active−HIGH)
enables data from A ports to B ports; Receive (active−LOW) enables
data from B to A ports. The Output Enable inputs (OEn), when HIGH,
disable both A and B ports by placing them in a HIGH Z condition.
