74LVT16373A

3.3V 16-bit transparent D-type latch (3-State)

1998 Feb 19

853-1780 18989

FEATURES

• 16-bit transparent latch

• 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

• 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

DESCRIPTION

The 74LVT16373A is a high-performance BiCMOS product

designed for VCC operation at 3.3V.

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 enable (E) input is High, the

Q outputs follow the data (D) inputs. When 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.
