9 / 28 page September 1993 9 Philips Semiconductors Product specification 4-Bit x 64-word FIFO register; 3-state 74HC/HCT7403 DC CHARACTERISTICS FOR 74HCT For the DC characteristics see “74HC/HCT/HCU/HCMOS Logic Family Specifications”, except that VOH and VOL are not valid for driver output. They are replaced by the values given below. Output capability: driver 8 mA. ICC category: LSI. Voltages are referenced to GND (ground = 0 V). DC CHARACTERISTICS FOR 74HCT Notes to the HCT DC Characteristics 1. The value of additional quiescent supply current ( ∆ICC) for a unit load of 1 is given in the family specifications. 2. To determine ∆ICC per input, multiply this value by the unit load coefficient shown in the table below. UNIT LOAD COEFFICIENT SYMBOL PARAMETER Tamb (°C) UNIT TEST CONDITION +25 −40 to +85 −40 to +125 VCC (V) VI OTHER MIN TYP MAX MIN MAX MIN MAX VOH HIGH level output voltage all outputs 4.4 4.5 − 4.4 − 4.4 − V 4.5 VIH or VIL IO = −20 µA VOH HIGH level output voltage driver outputs 3.98 4.32 − 3.84 − 3.7 − V 4.5 VIH or VIL IO = −8 mA VOL LOW level output voltage all outputs − 0 0.1 − 0.1 − 0.1 V 4.5 VIH or VIL IO = 20 µA VOL LOW level output voltage driver outputs − 0.15 0.26 − 0.33 − 0.4 V 4.5 VIH or VIL IO = 8 mA INPUT UNIT LOAD COEFFICIENT OE 1 SI 1.5 Dn 0.75 MR 1.5 SO 1.5 |
