DC CHARACTERISTICS FOR 74HC/HCT For 74HC: VCC − GND or VCC − VEE = 2.0, 4.5, 6.0 and 9.0 V For 74HCT: VCC − GND = 4.5 and 5.5 V; VCC − VEE = 2.0, 4.5, 6.0 and 9.0 V Notes to DC characteristics 1. At supply voltages (VCC − VEE) approaching 2.0 V, the analog switch ON-resistance becomes extremely non-linear. There it is recommended that these devices be used to transmit digital signals only, when using these supply voltages. 2. For test circuit measuring RON see Fig.8.
