74LVC2G14
Dual inverting Schmitt trigger with 5 V tolerant input
Rev. 04 — 4 September 2007
Product data sheet
1. General description
The 74LVC2G14 provides two inverting buffers with Schmitt-trigger action.
The inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of
this device in a mixed 3.3 V and 5 V environment. Schmitt-trigger action at the inputs
makes the circuit tolerant of slower input rise and fall time. 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
I Wide supply voltage range from 1.65 V to 5.5 V
I 5 V tolerant inputs for interfacing with 5 V logic
I High noise immunity
I Complies with JEDEC standard:
N JESD8-7 (1.65 V to 1.95 V)
N JESD8-5 (2.3 V to 2.7 V)
N JESD8B/JESD36 (2.7 V to 3.6 V)
I ESD protection:
N HBM JESD22-A114E exceeds 2000 V
N MM JESD22-A115-A exceeds 200 V
I ±24 mA output drive (VCC = 3.0 V)
I CMOS low power consumption
I Latch-up performance exceeds 250 mA
I Direct interface with TTL levels
I Unlimited rise and fall times
I Input accepts voltages up to 5 V
I Multiple package options
I Specified from −40 °C to +85 °C and −40 °C to +125 °C.
3. Applications
I Wave and pulse shaper
I Astable multivibrator
I Monostable multivibrator

[1] The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
[2] When VCC = 0 V (Power-down mode), the output voltage can be 5.5 V in normal operation.
[3] For SC-88 and SC-74A packages: above 87.5 °C the value of Ptot derates linearly with 4.0 mW/K.
For XSON6 packages: above 45 °C the value of Ptot derates linearly with 2.4 mW/K.

15. Application information
The slow input rise and fall times cause additional power dissipation, which can be
calculated using the following formula:
Padd = fi × (tr × ∆ICC(AV) + tf × ∆ICC(AV)) × VCC where:
Padd = additional power dissipation (µW);
fi = input frequency (MHz);
tr = input rise time (ns); 10 % to 90 %;
tf = input fall time (ns); 90 % to 10 %;
∆ICC(AV) = average additional supply current (µA).
∆ICC(AV) differs with positive or negative input transitions, as shown in Figure 12.
An example of a relaxation circuit using the 74LVC2G14 is shown in Figure 13.
