Functional Description
• Edge-rate control circuitry for significantly improved
noise characteristics
CY74FCT16373T and CY74FCT162373T are 16-bit D-type
latches designed for use in bus applications requiring high
speed and low power. These devices can be used as two
independent 8-bit latches or as a single 16-bit latch by con-
necting the Output Enable (OE) and Latch (LE) inputs.
Flow-through pinout and small shrink packaging aid in
simplifying board layout. The output buffers are designed with
power-off disable feature that allows live insertion of boards.
• Typical output skew < 250 ps
• ESD > 2000V
• TSSOP (19.6-mil pitch) and SSOP (25-mil pitch)
packages
• Industrial temperature range of 40°C to +85°C

• V = 5V 10%

CY74FCT16373T Features:
The CY74FCT16373T is ideally suited for driving
high-capacitance loads and low-impedance backplanes.
• 64 mA sink current, 32 mA source current
• Typical V
(ground bounce) <1.0V at V = 5V,
CC
OLP
The CY74FCT162373T has 24-mA balanced output drivers
with current limiting resistors in the outputs. This reduces the
need for external terminating resistors and provides for mini-
mal undershoot and reduced ground bounce. The
CY74FCT162373T is ideal for driving transmission lines.

Notes:
1. H = HIGH Voltage Level. L = LOW Voltage Level. X = Don’t Care. Z = High Impedance. Q0=Previous state of flip-flop.
2. Operation beyond the limits set forth may impair the useful life of the device. Unless otherwise noted, these limits are over the operating free-air temperature
range.
3. Unused inputs must always be connected to an appropriate logic voltage level, preferably either VCC or ground.
4. Typical values are at VCC=5.0V, TA= +25°C ambient.
5. This parameter is guaranteed but not tested.
6. Not more than one output should be shorted at a time. Duration of short should not exceed one second. The use of high-speed test apparatus and/or sample
and hold techniques are preferable in order to minimize internal chip heating and more accurately reflect operational values. Otherwise prolonged shorting of
a high output may raise the chip temperature well above normal and thereby cause invalid readings in other parametric tests. In any sequence of parameter
tests, IOS tests should be performed last.
7. Tested at +25°C.
