74VHCT32AFT

1. Functional Description

•

Quad 2-Input OR Gate

2. General

The 74VHCT32AFT is an advanced high speed CMOS 2-INPUT OR GATE 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.

The internal circuit is composed of 4 stages including buffer output, which provide high noise immunity and

stable output.

The input voltage are compatible with TTL output voltage.

This device may be used as a level converter for interfacing 3.3 V to 5 V system.

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, hot board insertion, etc.

Note: VCC = 0 V

3. Features

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

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

(3) High speed: tpd = 3.8 ns (typ.) at VCC = 5.0 V

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

(5) Compatible with TTL inputs: VIL = 0.8 V (max)

: VIH = 2.0 V (min)

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

(7) Balanced propagation delays: tPLH ≈ tPHL

(8) Low noise: VOLP = 0.8 V (max)

(9) Pin and function compatible with the 74 series (AC/HC/AHC/LV etc.) 32 type.

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

representative.

Note: Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or even

destruction.

Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the

significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even

if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum

ratings and the operating ranges.

Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook

(“HandlingPrecautions”/“DeratingConceptandMethods”)andindividualreliabilitydata(i.e. reliabilitytestreport

and estimated failure rate, etc).

Note 1: VCC = 0 V

Note 2: High (H) or Low (L) state. IOUT absolute maximum rating must be observed.

Note 3: VOUT < GND, VOUT > VCC

Note 4: 180 mW in the range of Ta = -40 to 85 . From Ta = 85 to 125  a derating factor of -3.25 mW/ shall be

applied until 50 mW.
