Dual inverting Schmitt-trigger with
5 V tolerant input
74LVC2G14
FEATURES
APPLICATIONS
• Wide supply voltage range from 1.65 V to 5.5 V
• 5 V tolerant input/output for interfacing with 5 V logic
• High noise immunity
• Wave and pulse shapers for highly noisy environments
• Astable multivibrators
• Monostable multivibrators.
• Complies with JEDEC standard:
– JESD8-7 (1.65 V to 1.95 V)
DESCRIPTION
– JESD8-5 (2.3 V to 2.7 V)
The 74LVC2G14 is a high-performance, low-power,
low-voltage, Si-gate CMOS device and superior to most
advanced CMOS compatible TTL families.
– JESD8B/JESD36 (2.7 V to 3.6 V).
• ±24 mA output drive (VCC = 3.0 V)
• CMOS low power consumption
• Latch-up performance exceeds 250 mA
• Direct interface with TTL levels
• Mulltiple package options
Inputs can be driven from either 3.3 V or 5 V devices. This
feature allows the use of this device as translator in a
mixed 3.3 V and 5 V environment.
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.
• ESD protection:
– HBM EIA/JESD22-A114-B exceeds 2000 V
– MM EIA/JESD22-A115-A exceeds 200 V.
The 74LVC2G14A provides two inverting buffers with
Schmitt-trigger action. It is capable of transforming slowly
changing input signals into sharply defined, jitter-free
output signals.
• Specified from −40 °C to +85 °C and
−40 °C to +125 °C.

Notes
1. CPD is used to determine the dynamic power dissipation (PD in µW).
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 Volts;
N = total switching outputs;
∑(CL × VCC2 × fo) = sum of outputs.
2. The condition is VI = GND to VCC
