Hc | HCT GENERAL DESCRIPTION tPHL/ propagation delay CL= 15 pF 1] 017) | ns tPLH nA, nB to nY Veco=5 Vv The 74HC/HCT 132 are high-speed Si-gate CMOS devices and are pin Cy input capacitance 3.5 3.5 pF compatible with low power Schottky TTL (LSTTL). They are specified in Cc power dissipation compliance with JEDEC standard no. 7A. PD capacitance per gate The 74HC/HCT132 contain four GND = 0 V; Tamb = 25 C: tr = te = 6 ns 2-input NAND gates which accept standard input signals. They are capable notes 1 and 2 24 20 pF of transforming slowly changing input Notes signals into sharply defined, jitter-free 1. Cpp is used to determine the dynamic power dissipation (Pp in uW): output signals, , ; Pp = Cpp x Vcc? x fi + (CL x VCC? x fo) where: The gate switches at different points fj; = input frequency in MHz CL output load capacitance in pF for positive and negative -going signals. The difference between the positive fo = output frequency in MHz vec supply voltage in V voltage V7+ and the negative voltage (CL x Voc x fol = sum of outputs V7_ is defined as the hysteresis 2. For HC_ the condition is V| = GND to Vcc voltage Vy. For HCT the condition is V| = GND to Vcc 1.5V PACKAGE OUTLINES 14-lead mini-pack; plastic (S014; SOT108A), 16-tead DIL; plastic (SOT38Z).
