74HC4851; 74HCT4851

8-channel analog multiplexer/demultiplexer with injection-current effect control

The 74HC4851; 74HCT4851 are high-speed Si-gate CMOS devices and are specified in compliance with JEDEC standard no. 7A.

The 74HC4851; 74HCT4851 are 8-channel analog multiplexers/demultiplexers 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). The devices feature injection-current effect control, which has excellent value in automotive applications where voltages in excess of the supply voltage are common.

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.

The injection-current effect control allows signals at disabled analog input channels to exceed the supply voltage without affecting the signal of the enabled analog channel. This eliminates the need for external diode/resistor networks typically used to keep the analog channel signals within the supply-voltage range.

Features and benefits

  • Injection-current cross coupling < 1 mV/mA

  • Wide supply voltage range from 2.0 V to 6.0 V for 74HC4851

  • Latch-up performance exceeds 100 mA per JESD 78 Class II level A

  • Low ON-state resistance:

    • 400 Ω (typical) at VCC = 2.0 V

    • 215 Ω (typical) at VCC = 3.0 V

    • 120 Ω (typical) at VCC = 3.3 V

    • 76 Ω (typical) at VCC = 4.5 V

    • 59 Ω (typical) at VCC = 6.0 V

  • ESD protection:

    • HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V

    • CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V

  • Multiple package options

  • Specified from -40 °C to +85 °C and -40 °C to +125 °C

Applications

  • Analog multiplexing and demultiplexing

  • Digital multiplexing and demultiplexing
