The 74HC4051; 74HCT4051 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 74HC4051; 74HCT4051 is an 8-channel analog multiplexer/demultiplexer 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. VCC and GND are the supply voltage pins for the digital control inputs (S0 to S2, and E). The VCC 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 VCC as a positive limit and VEE as a negative limit. VCC – VEE may not exceed 10.0 V. For operation as a digital multiplexer/demultiplexer, VEE is connected to GND (typically ground).
- Wide analog input voltage range from -5 V to +5 V
- Low ON resistance:
- 80 ? (typical) at VCC – VEE = 4.5 V
- 70 ? (typical) at VCC – VEE = 6.0 V
- 60 ? (typical) at VCC – VEE = 9.0 V
- Logic level translation: to enable 5 V logic to communicate with ±5 V analog signals
- Typical ‘break before make’ built-in
- ESD protection:
- HBM JESD22-A114F exceeds 2000 V
- MM JESD22-A115-A exceeds 200 V
- CDM JESD22-C101E exceeds 1000 V
- Multiple package options
- Specified from -40 °C to +85 °C and -40 °C to +125 °C
