General Description
IDT74FCT166245AT General Description
The FCT166245T 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 FCT166245T is suited for very low noise, point-to-point driving where there is a single receiver, or a light lumped load (<100pF). The buffers are designed to limit the output current to levels which will avoid noise and ringing on the signal lines without using external series terminating resistors. These parts have a ±8mA driver on the "A" Port and a +64/32mA driver on the "B" Port, making them ideal for interfacing noisy system busses to noise sensitive interfaces.
