74LVC32A
Quad 2-input OR gate
Rev. 5 — 17 November 2011
Product data sheet
1. General description
The 74LVC32A provides four 2-input OR gates.
Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of these
devices as translators in mixed 3.3 V and 5 V applications.
2. Features and benefits
5 V tolerant inputs for interlacing with 5 V logic
Wide supply voltage range from 1.2 V to 3.6 V
CMOS low power consumption
Direct interface with TTL levels
Complies with JEDEC standard:
JESD8-7A (1.65 V to 1.95 V)
JESD8-5A (2.3 V to 2.7 V)
JESD8-C/JESD36 (2.7 V to 3.6 V)
ESD protection:
HBM JESD22-A114F exceeds 2000 V
MM JESD22-A115-B exceeds 200 V
CDM JESD22-C101E exceeds 1000 V

(1) This is not a supply pin. The substrate is attached to this
pad using conductive die attach material. There is no
electrical or mechanical requirement to solder this pad.
However, if it is soldered, the solder land should remain
floating or be connected to GND.
