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
