74VHCT574A Octal D-Type Flip-Flop with 3-STATE Outputs
July 1997
Revised April 1999
74VHCT574A
Octal D-Type Flip-Flop with 3-STATE Outputs
General Description
The VHCT574A is an advanced high speed CMOS octal
flip-flop 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 flip-
flop is controlled by a clock input (CP) and an Output
Enable input (OE). When the OE input is HIGH, the eight
outputs are in a high impedance state.
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.
Note 1:
Outputs in OFF-State.
