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

74ALVT16373
FEATURES
•
16-bit transparent latch
•
5V I/O compatibile
•
3-State buffers
•
Output capability: +64mA/-32mA
•
TTL input and output switching levels
•
Input and output interface capability to systems at 5V supply
•
Bus-hold data inputs eliminate the need for external pull-up
resistors to hold unused inputs
DESCRIPTION
The 74ALVT16373 is a high-performance BiCMOS product
designed for V
CC
operation at 2.5V or 3.3V with I/O compatibility up
to 5V.
This device is a 16-bit transparent D-type latch with non-inverting
3-State bus compatible outputs. The device can be used as two
8-bit latches or one 16-bit latch. When latch enable (LE) input is
High, the Q outputs follow the data (D) inputs. When latch enable is
taken Low, the Q outputs are latched at the levels of the D inputs
one setup time prior to the High-to-Low transition.
•
Live insertion/extraction permitted
•
Power-up reset
•
Power-up 3-State
•
No bus current loading when output is tied to 5V bus
•
Latch-up protection exceeds 500mA per JEDEC Std 17
•
ESD protection exceeds 2000V per MIL STD 883 Method 3015
and 200V per Machine Model
