5 / 8 page September 1993 5 Philips Semiconductors Product specification Quad 2-input NAND Schmitt trigger 74HC/HCT132 DC CHARACTERISTICS FOR 74HCT For the DC characteristics see “74HC/HCT/HCU/HCMOS Logic Family Specifications”. Transfer characteristics are given below. Output capability: standard ICC category: SSI Notes to HCT types The value of additional quiescent supply current ( ∆I CC) for a unit load of 1 is given in the family specifications. To determine ∆ICC per input, multiply this value by the unit load coefficient shown in the table below. Transfer characteristics for 74HCT Voltages are referenced to GND (ground = 0 V) AC CHARACTERISTICS FOR 74HCT GND = 0 V; tr =tf = 6 ns; CL = 50 pF INPUT UNIT LOAD COEFFICIENT nA, nB 0.3 SYMBOL PARAMETER Tamb (°C) UNIT TEST CONDITIONS 74HCT VCC (V) WAVEFORMS +25 −40 to +85 −40 to +125 min. typ. max. min. max. min. max.
