74LVC1G27
Single 3-input NOR gate
Rev. 2 — 2 December 2016
Product data sheet
1. General description
The 74LVC1G27 provides one 3-input NOR function.
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.
Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall
time.
This device is fully specified for partial power-down applications using I
OFF
.
The I
OFF
circuitry disables the output, preventing the damaging backflow current through
the device when it is powered down.
2. Features and benefits
Wide supply voltage range from 1.65 V to 5.5 V
High noise immunity
Complies with JEDEC standard:
JESD8-7 (1.65 V to 1.95 V)
JESD8-5 (2.3 V to 2.7 V)
JESD8B/JESD36 (2.7 V to 3.6 V)
ESD protection:
HBM JESD22-A114F exceeds 2000 V
MM JESD22-A115-A exceeds 200 V
CDM JESD22-C101-C exceeds 1000 V
24
mA output drive (V
CC
= 3.0 V)
CMOS low power consumption
Latch-up performance exceeds 250 mA
Direct interface with TTL levels
Inputs accept voltages up to 5 V

The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
When V
CC
= 0 V (Power-down mode), the output voltage can be 5.5 V in normal operation.
For SC-88 and TSOP6 packages: above 87.5
C
the value of P
tot
derates linearly with 4.0 mW/K.
For XSON6 packages: above 118
C
the value of P
