Philips Semiconductors Product specification Hex inverting Schmitt-trigger with 5V tolerant input 74LVC14A FEATURES Wide supply voltage range of: 1.2 V to 3.6V @ 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 Wave and pulse shapers for highly noisy environments Astable multivibrators Monostabie multivibrators DESCRIPTION The 74LVC14<A 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.
