74VHC165FT

1. Functional Description

•

8-Bit Shift Register (P-IN, S-OUT)

2. General

The 74VHC165FT is an advanced high speed CMOS 8-BIT PARALLEL/SERIAL-IN, SERIAL-OUT SHIFT

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

low power dissipation.

It consists of parallel-in or serial-in, serial-out 8-bit shift register with a gated clock input. When the SHIFT/

LOAD input is held high, the serial data input is enabled and the eight frip-frops perform serial shifting with

each clock pulse.

When the SHIFT/LOAD input is held low, the parallel data is loaded synchronously into the register at positive

going transition of the clock pulse.

The CK-INH input should be shifted high only when the CK input is held high.

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 on 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 = 150 MHz (typ.) at VCC = 5 V

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

(5) High noise immunity: VNIH = VNIL = 28 % VCC (min)

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

(7) Balanced propagation delays: tPLH ≈ tPHL

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

(9) Pin and function compatible with 74 series (74AC/HC/AHC etc.) 165 type.

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

representative.
