74AUP2G34
Low-power dual buffer
Rev. 6 — 17 September 2015
Product data sheet
1. General description
The 74AUP2G34 provides two low-power, low-voltage buffers.
Schmitt trigger action at all inputs makes the circuit tolerant to slower input rise and fall
times across the entire VCC range from 0.8 V to 3.6 V.
This device ensures a very low static and dynamic power consumption across the entire
VCC range from 0.8 V to 3.6 V.
This device is fully specified for partial power-down applications using IOFF.
The IOFF 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 0.8 V to 3.6 V
High noise immunity
Complies with JEDEC standards:
JESD8-12 (0.8 V to 1.3 V)
JESD8-11 (0.9 V to 1.65 V)
JESD8-7 (1.2 V to 1.95 V)
JESD8-5 (1.8 V to 2.7 V)
JESD8-B (2.7 V to 3.6 V)
ESD protection:
HBM JESD22-A114F Class 3A exceeds 5000 V
MM JESD22-A115-A exceeds 200 V
CDM JESD22-C101E exceeds 1000 V
Low static power consumption; ICC = 0.9 A (maximum)
Latch-up performance exceeds 100 mA per JESD 78 Class II
Inputs accept voltages up to 3.6 V
Low noise overshoot and undershoot < 10 % of VCC
IOFF circuitry provides partial Power-down mode operation
Multiple package options
Specified from 40 C to +85 C and 40 C to +125 C
