74VHCV574FT

1. Functional Description

•

Octal Schmitt D-Type Flip-Flop with 3-State Outputs

2. General

The 74VHCV574FT is 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 (CK) and an output enable input (OE).

When the OE input is high, the eight outputs are in a high impedance state.

Input pin have hysteresis between the positive-going and negative-going thresholds. Thus the 74VHCV574FT is

capable of squaring up transitions of slowly changing input signals and provides an improved noise immunity.

Input protection and output circuit ensure that 0 to 5.5 V can be applied to the input and output (Note) pins

without regard to the supply voltage. These structure prevents device destruction due to mismatched supply and

input/output voltages such as battery back up, etc.

Note: Output in off-state.

3. Features

(1) AEC-Q100 (Rev. H) (Note 1)

(2) Wide operating temperature range: Topr = -40 to 125 

(3) High speed: fMAX = 180 MHz (typ.) at VCC = 5.0 V

(4) Low power dissipation: ICC = 2.0 µA (max) at Ta = 25

(5) Wide operating voltage range: VCC(opr) = 1.8 V to 5.5 V

(6) Output current: |IOH|/IOL = 16 mA (min)(VCC = 4.5 V)

(7) Power-down protection is provided on all inputs and outputs.

(8) Pin and function compatible with the 74 series (74AC/HC/AHC/LV etc.) 574 type.

Note 1: This device is compliant with the reliability requirements of AEC-Q100. For details, contact your Toshiba sales

representative.
