2 / 9 page 1998 Jul 08 2 Philips Semiconductors Product specification Hex non-inverting precision Schmitt-trigger 74HC7014 FEATURES • Operating voltage 3 to 6 V • Output capability: standard • category: SSI APPLICATIONS • Wave and pulse shapers for highly noisy environments DESCRIPTION The 74HC7014 is a high-speed Si-gate CMOS device. It is specified in compliance with JEDEC standard no. 7A. The 74HC7014 provides six precision Schmitt-triggers with non-inverting buffers. It is capable of transforming slowly changing input signals into sharply defined, jitter-free output signals. The precisely defined trigger levels are lying in a window between 0.55 × V CC and 0.65 × VCC. This makes the circuit suitable to operate in a highly noisy environment. Input shorts are allowed to −1.5 V and 16 V without disturbing other channels. FUNCTION TABLE Note 1. H = HIGH voltage level L = LOW voltage level INPUT OUTPUT nA nY LL HH QUICK REFERENCE DATA GND = 0 V; Tamb = 25 °C; tr = tf = 6 ns Notes to the quick reference data 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. fo = output frequency in MHz. CL = output load capacitance in pF. VCC = supply voltage in V. ∑ (CL × VCC2 × fo) = sum of outputs. 2. For HC the condition is VI = GND to VCC.
