Engineering Selection Recommendations

The TMUX1309PWR is the designated substitute for the SN74HC4852DGVR based on functional equivalence and product lifecycle status. Both devices are manufactured by Texas Instruments and maintain ROHS3 compliance with MSL rating of 1 (Unlimited).

The SN74HC4852DGVR is in Last Time Buy status, indicating discontinued production. The TMUX1309PWR maintains Active product status, ensuring long-term availability and supply chain continuity. Both devices share identical core switching specifications: SP4T topology, 4:1 multiplexer/demultiplexer configuration, 2 circuits, and 195Ohm maximum on-state resistance.

Package compatibility requires attention: the SN74HC4852DGVR uses 16-TFSOP packaging while the TMUX1309PWR uses 16-TSSOP packaging. Both maintain the same 4.40mm width and 16-pin configuration, supporting direct PCB layout compatibility with standard surface mount assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the TMUX1309PWR directly replace the SN74HC4852DGVR in existing designs?

A: Yes, the TMUX1309PWR is functionally equivalent for the core switching application. Both devices provide SP4T 4:1 multiplexer/demultiplexer functionality with 2 circuits and 195Ohm on-state resistance. Package footprints are compatible (16-pin, 4.40mm width). Verify PCB assembly compatibility with your manufacturing partner for TFSOP-to-TSSOP transition if required.

Q: What are the key differences between these two parts?

A: The TMUX1309PWR offers improved electrical performance: faster switch times (32ns/40ns vs. 39ns/78ns), lower leakage current (1nA typical vs. 200nA maximum), reduced channel capacitance (14pF/7pF vs. 22pF), and extended operating temperature range (-40°C to 125°C vs. -40°C to 85°C). The TMUX1309PWR maintains Active product status while the SN74HC4852DGVR is Last Time Buy.

Q: Are there supply voltage compatibility concerns?

A: The SN74HC4852DGVR operates at 2V to 6V single supply. The TMUX1309PWR operates at 1.62V to 5.5V single supply. Applications operating above 5.5V or below 1.62V require design review. For applications within the 2V to 5.5V overlap range, both devices are compatible.

Q: What packaging considerations apply to this substitution?

A: The SN74HC4852DGVR uses 16-TFSOP packaging; the TMUX1309PWR uses 16-TSSOP packaging. Both are 16-pin surface mount packages with 4.40mm width. TFSOP and TSSOP packages have compatible footprints for standard PCB assembly. Confirm with your PCB design and assembly documentation before implementation.

Q: Are both parts RoHS compliant?

A: Yes, both the SN74HC4852DGVR and TMUX1309PWR are ROHS3 compliant with MSL rating of 1 (Unlimited). Both are suitable for applications requiring RoHS compliance and have unlimited moisture sensitivity level ratings.
