MC74LCX16245/D
MC74LCX16245
Low-Voltage CMOS
16-Bit Transceiver
With 5 V−Tolerant Inputs and Outputs
(3−State, Non−Inverting)
The MC74LCX16245 is a high performance, non−inverting 16−bit
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
I
specification of 5.5 V allows MC74LCX16245
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.
The 4.5 ns maximum propagation delays support high performance
applications. Current drive capability is 24 mA at both A and B ports.
The Transmit/Receive (T/R
n) 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.
