1. Functional Description

•

Octal D-Type Flip-Flop with Clear

2. General

The 74VHC9273FT is an advanced high speed CMOS OCTAL D-TYPE FLIP FLOP fabricated with silicon gate

C2MOS technology.

It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS

low power dissipation.

When the CLR input is held "L", the Q outputs are at a low logic level independent of the other inputs.

The CLR input and CK input have hysteresis between the positive-going and negative-going thresholds. Thus

noise immunity.

It is easy to wire on the board because Input terminals are at the opposite side of Output terminals.

An input protection circuit ensures that 0 to 5.5 V can be applied to the input pins without regard to the supply

voltage. This device can be used to interface 5 V to 3 V systems and two supply systems such as battery back up.

This circuit prevents device destruction due to mismatched supply and input voltages.

3. Features

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

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

(3) High speed: fMAX = 195 MHz (typ.) at VCC = 5.0 V

(4) Low power dissipation: ICC = 4.0 µA (max) at Ta = 25

(5) Power-down protection is provided on all inputs.

(6) Balanced propagation delays: tPLH ≈ tPHL

(7) Wide operating voltage range: VCC(opr) = 2.0 V to 5.5 V

(8) Function compatible with 74VHC273

(9) Input terminals are at the opposite side of Output terminals

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

representative.
