Important notice
Dear Customer,
On 7 February 2017 the former NXP Standard Product business became a new company with the
tradename Nexperia. Nexperia is an industry leading supplier of Discrete, Logic and PowerMOS
semiconductors with its focus on the automotive, industrial, computing, consumer and wearable
application markets
In data sheets and application notes which still contain NXP or Philips Semiconductors references, use
the references to Nexperia, as shown below.
Instead of http://www.nxp.com, http://www.philips.com/ or http://www.semiconductors.philips.com/,
use http://www.nexperia.com
Instead of sales.addresses@www.nxp.com or sales.addresses@www.semiconductors.philips.com, use

74ALVT16823
18-bit bus-interface D-type flip-flop with reset and enable;
3-state
Rev. 04 — 2 August 2005
Product data sheet
1. General description
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.
2. Features
■ 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

This parameter is valid for any VCC between 0 V and 1.2 V with a transition time of up to 10 ms. From VCC = 1.2 V to VCC = 2.5 V ± 0.2 V
a transition time of 100 µs is permitted. This parameter is valid for Tamb = 25 °C only.
[6]
ICC is measured with outputs pulled up to VCC or pulled down to ground.
[7]
This is the increase in supply current for each input at the specified voltage level other than VCC or GND.
[8]
All typical values are at VCC = 3.3 V and Tamb = 25 °C.
[9]
This is the bus hold overdrive current required to force the input to the opposite logic state.
