74AXP2G34
Low-power dual buffer
Rev. 1 — 11 November 2015
Product data sheet
1. General description
The 74AXP2G34 is a dual buffer.
Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall
times.
This device ensures very low static and dynamic power consumption across the entire
VCC range from 0.7 V to 2.75 V. It is fully specified for partial power down applications
using IOFF. The IOFF circuitry disables the output, preventing the potentially damaging
backflow current through the device when it is powered down.
2. Features and benefits
Wide supply voltage range from 0.7 V to 2.75 V
Low input capacitance; CI = 0.5 pF (typical)
Low output capacitance; CO = 1.0 pF (typical)
Low dynamic power consumption; CPD = 2.4 pF at VCC = 1.2 V (typical)
Low static power consumption; ICC = 0.6 A (85 C maximum)
High noise immunity
Complies with JEDEC standard:
JESD8-12A.01 (1.1 V to 1.3 V)
JESD8-11A.01 (1.4 V to 1.6 V)
JESD8-7A (1.65 V to 1.95 V)
JESD8-5A.01 (2.3 V to 2.7 V)
ESD protection:
HBM ANSI/ESDA/JEDEC JS-001 Class 2 exceeds 2 kV
CDM JESD22-C101E exceeds 1000 V
Latch-up performance exceeds 100 mA per JESD 78 Class II
Inputs accept voltages up to 2.75 V
Low noise overshoot and undershoot < 10 % of VCC
IOFF circuitry provides partial Power-down mode operation
Multiple package options

CPD is used to determine the dynamic power dissipation (PD in W).
PD = CPD VCC2 fi N + CL VCC2 fo where:
fi = input frequency in MHz;
fo = output frequency in MHz;
CL = output load capacitance in pF;
VCC = supply voltage in V;
N = number of inputs switching.
