IDT54T

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 terminals for FCT162XXXT AND FCT166XXXT (A-Port).

The IDT54T 16-bit transceiver is built using advanced dual metal CMOS technology. These high-speed, low-power transceivers are ideal for synchronous communication between two buses (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) overrides the direction control and disables both ports. All inputs are designed with hysteresis for improved noise margin.

The IDT54T has balanced output drive with current limiting resistors. This offers low ground bounce, minimal undershoot, and controlled output fall timesreducing the need for external series terminating resistors. The IDT54T is a plug-in replacement for the FCT16245T and ABT16245 for on-board interface applications.
