Overview
Integrated Device Technology, Inc.
FAST CMOS 16-BIT BUS IDT54/74FCT16646T/AT/CT/ET IDT54/74FCT162646T/AT/CT/ET TRANSCEIVER/ REGISTERS (3-STATE) 74FCT162646T/AT/CT/ET 16-bit registered transceivers are built using advanced dual metal CMOS technology.
These high-speed, low-power devices are organized as two independent 8-bit bus transceivers with 3-state D-type registers.
The control circuitry is organized for multiplexed transmission of data between A bus and B bus either directly or from the internal storage registers.
Each 8-bit transceiver/register features direction control (xDIR), over-riding Output Enable control (xOE) and Select lines (xSAB and xSBA) to select either real-time data or stored data.
Separate clock inputs are provided for A and B port registers.
Data on the A or B data bus, or both, can be stored in the internal registers by the LOW-to-HIGH transitions at the appropriate clock pins.
Flowthrough organization of signal pins simplifies layout.
All inputs are designed with hysteresis for improved noise margin.
The IDT54/74FCT16646T/AT/CT/ET 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 IDT54/74FCT162646T/AT/CT/ET 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 IDT54/74FCT162646T/AT/CT/ET are plug-in replacements for the IDT54/74FCT16646T/AT/CT/ET and 54/74ABT16646 for on-board bus interface applications.
