The 74ALVT16823 18-bit bus interface register is designed to eliminate the extra packages required to buffer existing registers and provide extra data width for wider data/address paths of buses carrying parity.

The 74ALVT16823 has two 9-bit wide buffered registers with clock enable (pin nCE) and master reset (pin nMR) which are ideal for parity bus interfacing in high microprogrammed systems.

The registers are fully edge-triggered. The state of each D input, one set-up time before the LOW-to-HIGH clock transition is transferred to the corresponding Q output of the flip-flop.

It is designed for VCC operation from 2.5 V to 3.0 V with I/O compatibility to 5 V.

Features and benefits

  • Two sets of high speed parallel registers with positive edge-triggered D-type flip-flops
  • 5 V I/O compatible
  • Ideal where high speed, light loading, or increased fan-in are required with MOS microprocessors
  • Bus hold data inputs eliminate the need for external pull-up resistors to hold unused inputs
  • Live insertion and extraction permitted
  • Power-up 3-state
  • Power-up reset
  • No bus current loading when output is tied to 5 V bus
  • Output capability: +64 mA to -32 mA
  • Latch-up protection:
    • JESD78: exceeds 500 mA
  • ESD protection:
    • MIL STD 883, method 3015: exceeds 2000 V
    • Machine Model: exceeds 200 V
