NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.
2. All device terminals except FCT162XXXT and FCT166XXXT (A-Port) Output and I/O terminals.
3. Output and I/O terminals for FCT162XXXT and FCT166XXXT (A-Port).



Description

The 16-bit transceivers of the 74FCT166245T are built using advanced dual metal CMOS technology. These high-speed, low-power transceivers are ideal for synchronous communication between two busses (A and B). The Direction and Output Enable controls operate these devices as either two independent 8-bit transceivers or one 16-bit transceiver. The direction control pin (xDIR) controls the direction of data flow. The output enable pin (xOE) of the 74FCT166245T overrides the direction control and disables both ports. All inputs are designed with hysteresis for improved noise margin.

The 74FCT166245T are ideally suited for driving high-capacitance loads and low-impedance backplanes. The output buffers are designed with power off disable capability to allow "live insertion" of boards when used as backplane drivers.

The 74FCT166245T have balanced output drive with current limiting resistors. This offers low ground bounce, minimal undershoot, and controlled output fall times reducing the need for external series terminating resistors. The FCT162245T are plug-in replacements for the FCT16245T and ABT16245 for on-board interface applications.

The 74FCT166245T are suited for very low noise, point-topoint driving where there is a single receiver, or a light lumped
