1. General description
The 74LVC14A provides six inverting buffers with Schmitt trigger input. It is capable of
transforming slowly-changing input signals into sharply defined, jitter-free output signals.
The inputs switch at dif ferent points for positive and ne gative-going signals. The dif ference
between the po sit ive vo ltage VT+ and the negative voltage VT is defined as the input
hysteresis voltage VH.
Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of this
device as a translator in mixed 3.3 V and 5 V applications.
2. Features and benefits
Wide supply voltage range from 1.2 V to 3.6 V
5 V tolerant input for interfacing with 5 V logic
CMOS low-power consumption
Direct interface with TTL levels
Unlimited input rise and fall times
Inputs accept voltages up to 5.5 V
Complies with JEDEC standard JESD8-C/JESD36 (2.7 V to 3.6 V)
ESD protection:
HBM JESD22-A114F exceeds 2000 V
MM JESD22-A115 -B ex ce eds 20 0 V
CDM JESD22-C101E exceeds 1000 V
Multiple package options
Specified from 40 C to +85 C and from 40 C to +125 C
3. Applications
Wave and pulse shapers for highly noisy environments
Astable multivibrators
Monostable multivibrators

(1) This is not a supply pin. The substrate is attached to this
pad using conductive die attach material. There is no
electrical or mechanical requirement to solder this pad.
However, if it is soldered, the solder land should remain
