AT16373

Features

Fastest Propagation Speeds in the Industry TPD (F grade) = 2.5 ns, TPD (G grade) = 2.0 ns

Maximum derating for capacitive loads 1.5ns/100 pF (F grade) and 1.1ns/100 pF (G grade)

Very low ground bounce < 0.6V @ VCC=5.00V, Ta=25°C

Excellent noise rejection

Typical output skew 0.25ns

Bus Hold circuitry to retain last active state during Tri-state

Available in SSOP and TSSOP packages

Description

Atmel’s AT16373 devices provide maximum speed in temporary data storage. They can be operated as either two separate 8 bit latches or as a single 16-bit latch by use of the output enable and the latch enable. The AT16373 has very low ground bounce and excellent input noise rejection, giving the user stable signals in a high speed environment. These devices can drive very large loads while operating in a high speed transparent mode.

Note: 1. This 8-bit latch function is repeated a second time on each device.

*NOTICE: Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

Notes: 1. Minimum voltage is -0.6V dc which may undershoot to -2.0V for pulses of less than 20 ns. Maximum output pin voltage is VCC +0.75V dc which may overshoot to +7.0V for pulses of less than 20 ns.

Applicable over recommended operating range from Ta = 0°C to +70°C, V CC = +5.0V +/- 5% (unless otherwise noted)
