They are specified in compliance with JEDEC standard no. 7A. The 74HC/HCT132 contain four 2-input NAND gates which accept standard input signals. They are capable of transforming slowly changing input signals into sharply defined, jitter-free output signals. The gate switches at different points for positive and negative-going signals. The difference between the positive voltage VT+ and the negative voltage VT- is defined as the hysteresis voltage VH. QUICK REFERENCE DATA GND = 0 V; Tamb = 25 C; tr = tf = 6 ns TYPICAL SYMBOL tPHL/ tPLH CI CPD 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 fo = output frequency in MHz (CL x VCC2 x fo) = sum of outputs CL = output load capacitance in pF VCC = supply voltage in V 2.

September 1993 7 Philips Semiconductors Product specification Quad 2-input NAND Schmitt trigger Application information 74HC/HCT132 The slow input rise and fall times cause additional power dissipation, this can be calculated using the following formula: Pad = fi x (tr x ICCa + tf x ICCa) x VCC. Where: Pad fi tr tf ICCa = additional power dissipation (W) = input frequency (MHz) = input rise time (ns); 10% - 90% = input fall time (ns); 10% - 90% = average additional supply current (A) Average ICCa differs with positive or negative input transitions, as shown in Figs 14 and 15. Fig.14 Average ICC for HC Schmitt trigger devices; linear change of Vi between 0.1 VCC to 0.9 VCC. Fig.15 Average ICC for HCT Schmitt trigger devices; linear change of Vi between 0.1 VCC to 0.9 VCC.
