74VHC574
Octal D-Type Flip-Flop with 3-STATE Outputs
General Description
The VHC574 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 maintaining 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.
An input protection circuit ensures that 0V to 7V can be
applied to the input pins without regard to the supply volt-
age. This device can be used to interface 5V to 3V systems
and two supply systems such as battery back up. This cir-
cuit prevents device destruction due to mismatched supply
and input voltages.
Features
s High Speed: tPD = 5.6 ns (typ) at VCC = 5V
s High Noise Immunity: VNIH = VNIL = 28% VCC (Min)
s Power Down Protection is provided on all inputs
s Low Noise: VOLP = 0.6V (typ)
s Low Power Dissipation: ICC = 4 µA (Max) @ TA = 25°C

Functional Description
The VHC574 consists of eight edge-triggered flip-flops with
individual D-type inputs and 3-STATE true outputs. The
buffered clock and buffered Output Enable are common to
all flip-flops. The eight flip-flops will store the state of their
individual D inputs that meet the setup and hold time
requirements on the LOW-to-HIGH Clock (CP) transition.
With the Output Enable (OE) LOW, the contents of the
eight flip-flops are available at the outputs. When the OE is
HIGH, the outputs go to the high impedance state. Opera-
tion of the OE input does not affect the state of the flip-
flops.

Note 1: Absolute Maximum Ratings are values beyond which the device
may be damaged or have its useful life impaired. The databook specifica-
tions should be met, without exception, to ensure that the system design is
reliable over its power supply, temperature, and output/input loading vari-
ables. Fairchild does not recommend operation outside databook specifica-
tions.
Note 2: Unused inputs must be held HIGH or LOW. They may not float.
