Overview
The Nexperia 74HC4351D,652 is an 8-channel analog multiplexer/demultiplexer with address latches in a SO20 package. It operates on a single supply voltage from 2.0 V to 10.0 V or dual supplies up to ±5 V. The device features three digital select inputs (S0-S2), eight independent I/Os (Yn), and one common I/O (Z). It includes two enable inputs (E1 active LOW, E2 active HIGH) and a latch enable input (LE). Static characteristics include low ON resistance (typically 80 Ω at 4.5 V) and high OFF-state isolation. Dynamic performance specifies propagation delays of approximately 12 ns maximum at 4.5 V.
Feature Summary
- Integrated address latches for stable channel selection
- Wide analog signal range supporting bipolar voltages
- Built-in logic level translation for 5 V compatibility
- High electrostatic discharge protection ratings
Applications
- Analog multiplexing and demultiplexing
- Digital multiplexing and demultiplexing
- Signal gating
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current production status. Confirm that the SO20 package variant matches the required PCB footprint dimensions. Ensure compliance with RoHS directives and check for any end-of-life notifications regarding this specific part number before finalizing procurement plans.
Selection Notes
Select the 74HC4351D when a wide analog voltage range and integrated latching are required. Compare ON resistance specifications against the target signal amplitude to ensure minimal attenuation. Verify that the operating temperature range meets the environmental requirements of the application design.
Part Context
This component belongs to the 74HC/HCT logic family of analog switches. It serves as a single-pole octal-throw switch suitable for routing multiple analog or digital signals to a common destination. The device provides a compact solution for signal path management in mixed-signal systems requiring precise channel control.
Replacement Considerations
The 74HCT4351D offers identical functionality with TTL-compatible input levels. The 74HC4351PW is available in a TSSOP20 package for space-constrained designs. Verify pinout compatibility and electrical parameters before substituting these variants.
