Product specification
Hex inverting Schmitt-trigger with 5V tolerant input
74LVC14A
FEATURES
* Wide supply voltage range of: 1.2 V to 3.6 V * In accordance with JEDEC standard no. 8-1A * Inputs accept voltages up to 5.5 V * CMOS low power consumption * Direct interface with TTL levels
APPLICATIONS
DESCRIPTION
The 74LVC14A is a high-performance, low power, low-voltage Si-gate CMOS device and superior to most advanced CMOS compatible TTL families. Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of these devices as translators in a mixed 3.3 V/5 V environment. The 74LVC14A provides six inverting buffers with Schmitt-trigger action. It is capable of transforming slowly changing input signals into sharply defined, jitter-free output signals.
* Wave and pulse shapers for highly noisy environments * Astable multivibrators * Monostable multivibrators
QUICK REFERENCE DATA
GND = 0 V; Tamb = 25C; tr tf 2.5 ns SYMBOL tPHL/tPLH CI CPD PARAMETER Propagation delay g y nA to nY Input capacitance Power dissipation capacitance per gate Notes 1 and 2 CONDITIONS CL = 50 pF; VCC = 3.3 V TYPICAL 4 3.5 25 UNIT ns pF pF
NOTES: 1. CPD is used to determine the dynamic power dissipation (PD in W) PD = CPD x VCC2 x fi ) (CL x VCC2 x fo) where: fi = input frequency in MHz; CL = output load capacity in pF; fo = output frequency in MHz; VCC = supply voltage in V; (CL x VCC2 x fo) = sum of the outputs. 2. The condition is VI = GND to VCC.

NOTES: 1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. 2. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
