Overview
The 74HC4351N,652 is an 8-channel analog multiplexer/demultiplexer with address latches manufactured by Nexperia. It features three digital select inputs (S0 to S2), two enable inputs (E1 and E2), and a latch enable input (LE). The device supports a wide analog input voltage range of ±5 V and provides logic level translation for 5 V logic interfacing with ±5 V analog signals. Typical ON resistance values are 80 Ω at VCC−VEE=4.5 V, 70 Ω at 6.0 V, and 60 Ω at 9.0 V. Maximum ON resistance reaches 270 Ω at minimum supply voltages. The component operates within a temperature range of -40 °C to +85 °C or +125 °C.
Feature Summary
- Built-in address latches allow selection data to be stored independently of the select inputs.
- Logic level translation capability enables communication between 5 V digital logic and ±5 V analog signals.
- Typical 'break before make' switching action prevents signal shorting during channel transitions.
Applications
- Analog multiplexing and demultiplexing
- Digital multiplexing and demultiplexing
- Signal gating
Procurement Notes
Verify that the ordering suffix matches the required package type and tape/reel specifications. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the supplier source is authorized to guarantee component authenticity and traceability.
Selection Notes
Select this component when an 8-channel analog switch with latched address inputs is required. Verify that the supply voltage difference (VCC-VEE) meets the desired ON resistance performance. Check if the ±5 V analog signal range aligns with system requirements.
Part Context
This part belongs to the 74HC/HCT4351 family of high-speed Si-gate CMOS devices. It complies with JEDEC standard no. 7A. The business was transferred from NXP Semiconductors to Nexperia B.V. in February 2017.
Replacement Considerations
The 74HCT4351 is a compatible variant within the same family offering TTL-compatible logic levels. Other 8-channel analog switches may serve as alternatives if latch functionality is not required.
FAQ
How does the latch enable input function?
When LE is LOW, the latch stores the state of the select inputs. When LE is HIGH, the latch is transparent, allowing changes in select inputs to immediately affect the switch state.
What is the maximum supply voltage difference allowed?
The difference between VCC and VEE must not exceed 10.0 V.
Can this device operate with a single supply?
Yes, for digital multiplexing applications, VEE can be connected to GND (0 V).
