2 / 12 page Philips Semiconductors Product specification 74LV14 Hex inverting Schmitt-trigger 2 1998 Apr 20 853–1895 19256 FEATURES • Wide operating voltage: 1.0 to 5.5 V • Optimized for Low Voltage applications: 1.0 to 3.6 V • Accepts TTL input levels between V CC = 2.7 V and VCC = 3.6 V • Typical V OLP (output ground bounce) < 0.8 V at VCC = 3.3 V, Tamb = 25°C. • Typical V OHV (output VOH undershoot) > 2 V at VCC = 3.3 V, Tamb = 25°C. • Output capability: standard • I CC category: SSI APPLICATIONS • Wave and pulse shapers for highly noisy environments DESCRIPTION The 74LV14 is a low-voltage Si-gate CMOS device and is pin and function compatible with 74HC/HCT14. The 74LV14 provides six inverting buffers with Schmitt-trigger action. It is capable of transforming slowly changing input signals into sharply defined, jitter-free output signals. QUICK REFERENCE DATA GND = 0 V; Tamb = 25°C; tr = tf ≤ 2.5 ns SYMBOL PARAMETER CONDITIONS TYPICAL UNIT tPHL/tPLH Propagation delay nA to nY CL = 15 pF; VCC = 3.3 V 13 ns CI Input capacitance 3.5 pF CPD Power dissipation capacitance per gate See Notes 1 and 2 15 pF 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 capacitance 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. ORDERING INFORMATION PACKAGES TEMPERATURE RANGE OUTSIDE NORTH AMERICA NORTH AMERICA PKG.
