LC74FCT164245, 74FCT164245T

Fast 16-Bit CMOS Bidirectional Transceiver

(Supporting 3.3 to 5 V Operation)

Overview

The LC74FCT164245 and LC74FCT164245T 16-bit 3.3-

to-5 V translators are fabricated in an advanced two-

metal-layer CMOS technology. These high-speed low-

power transceivers are designed to be used as interfaces

between 3.3 V and 5 V busses in 3.3/5 V dual power

supply systems. The use of these products allows system

designers to interface TTL-compatible 3.3 V components

to 5 V components. The directionality and output enable

control in these products is designed to allow them to be

used as either two independent 8-bit transceivers or as a

single 16-bit transceiver. In use, the A port is interfaced to

the 3.3 V bus and the B port to the 5 V bus. The direction

control pin (× DIR) controls the data flow direction and

the output enable pin (× OE) disables directionality

control and disables both ports. These control signals can

be driven from either 3.3 V system or 5 V system devices.

The LC74FCT164245T is optimal for driving large-

capacitance loads and low-impedance loads. These output

buffers can also be used as an interface between a dual-

power-supply system and external 5 V system equipment.

The LC74FCT164245 provides a balanced output drive

function that incorporates 25 Ω (typical value) supply

terminating resistors in each output to minimize ground

bounce. The LC74FCT164245 features an inter-rail output

amplitude and a control-type output edge rate. These

features aim at improved signal quality. The

LC74FCT164245 is optimal for use in on-board bus

interfaces, and in particular, memory data buses.
