1 Product data sheet 1. General description 2. Features 3. Applications The is a high-speed Si-gate CMOS device and is pin compatible with Low-power Schottky TTL (LSTTL). The device is specified in compliance with JEDEC standard no. 7A. The is an with three digital select inputs (S0 to S2), an active-low enable input (E), eight independent inputs/outputs (Y0 to Y7) and a common input/output (Z). With E LOW, one of the eight switches is selected (low impedance ON-state) by S0 to S2. With E HIGH, all switches are in the high-impedance OFF-state, independent of S0 to S2. V CC and GND are the supply voltage pins for the digital control inputs (S0 to S2, and E). The V CC to GND ranges are 2.0 V to 10.0 V for 74HC4051 and 4.5 V to 5.5 V for 74HCT4051. The analog inputs/outputs (Y0 to Y7, and Z) can swing between V CC as a positive limit and V EE as a negative limit. V CC V EE may not exceed 10.0 V. For operation as a digital multiplexer/demultiplexer, V EE is connected to GND (typically ground). Wide analog input voltage range: ±5 V Low ON-state resistance: 80 Ω (typical) at V CC V EE = 4.5 V 70 Ω (typical) at V CC V EE = 6.0 V 60 Ω (typical) at V CC V EE = 9.0 V Logic level translation: To enable 5 V logic to communicate with ±5 V analog signals Typical break before make built in Analog multiplexing and demultiplexing Digital multiplexing and demultiplexing Signal gating

If the switch current flows into terminal Z, no V CC current will flow out of terminals Yn. In this case there is no limit for the voltage drop across the switch, but the voltages at Yn and Z may not exceed V CC or V EE.
