Octal D-Type Latch with 3-STATE Outputs

General Description

Features

The VHCT573A 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 maintain-

ing the CMOS low power dissipation. This 8-bit D-type

latch is controlled by a Latch Enable input (LE) and an Out-

put Enable input (OE). When the OE input is HIGH, the

eight outputs are in a high impedance state.

■ High speed: t_PD7.7 ns (typ) at T_A25 C

■ High Noise Immunity: V_IH2.0V, V_IL0.8V

■ Power Down Protection is provided on all inputs and

outputs

■ Low Noise: V_OLP1.6V (max)

■ Low Power Dissipation:

I_CC

4 A (max) @ T_A25 C

Protection circuits ensure that 0V to 7V can be applied to

the input and output (Note 1) pins without regard to the

supply voltage. This device can be used to interface 3V to

5V systems and two supply systems such as battery back

up. This circuit prevents device destruction due to mis-

matched supply and input voltages.

■ Pin and function compatible with 74HCT573

Note 1: Outputs in OFF-State.
