INTEGRATED CIRCUITS 74LVC14A Hex inverting Schmitt-trigger with 5V tolerant input Product specification 1998 Apr 28 Philips Semiconductors Product specification Hex inverting Schmitt-trigger with 5V tolerant input FEATURES 74LVC14A DESCRIPTION • 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 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. APPLICATIONS • Wave and pulse shapers for highly noisy environments • Astable multivibrators • Monostable multivibrators QUICK REFERENCE DATA GND = 0 V; Tamb = 25°C; tr ≤ tf ≤ 2.5 ns PARAMETER SYMBOL tPHL/tPLH Propagation delayy g nA to nY CI Input capacitance CPD CONDITIONS TYPICAL UNIT 4 ns 3.5 pF 25 pF CL = 50 pF; VCC = 3.3 V Power dissipation capacitance per gate Notes 1 and 2 NOTES: 1. CPD is used to determine the dynamic power dissipation (PD in µW) PD = CPD × VCC2 × fi (CL × VCC2 × fo) where: fi = input frequency in MHz; CL = output load capacity in pF; fo = output frequency in MHz; VCC = supply voltage in V; (CL × VCC2 × fo) = sum of the outputs. 2. The condition is VI = GND to VCC.
