74VHC573
Octal D-Type Latch with 3-STATE Outputs
Features
■ High Speed: tPD = 5.0ns (Typ.) at VCC = 5V
■ High Noise Immunity: VNIH = VNIL = 28% VCC (Min.)
■ Power Down Protection is provided on all inputs
■ Low Noise: VOLP = 0.6V (Typ.)
■ Low Power Dissipation: ICC = 4A (Max.) @ TA = 25°C
■ Pin and function compatible with 74HC573
General Description
The VHC573 is an advanced high speed CMOS octal
latch with 3-STATE output fabricated with silicon gate
CMOS technology. It achieves the high speed operation
similar to equivalent Bipolar Schottky TTL while main-
taining the CMOS low power dissipation. This 8-bit
D-type latch is controlled by a latch enable input (LE)
and an Output Enable input (OE). When the OE input is
HIGH, the eight outputs are in a high impedance state.
An input protection circuit ensures that 0V to 7V can be
applied to the input pins without regard to the supply
voltage. This device can be used to interface 5V to 3V
systems and two supply systems such as battery back
up. This circuit prevents device destruction due to mis-
matched supply and input voltages.
Ordering Information
Surface mount packages are also available on Tape and Reel. Specify by appending the suffix letter “X” to the
ordering number. Pb-Free package per JEDEC J-STD-020B.
