Overview
The TS5N412PWR is a 4-bit 1-of-2 FET multiplexer/demultiplexer and high-bandwidth bus switch manufactured by Texas Instruments. It operates within a supply voltage range of 4.75 V to 5.25 V and supports data input/output voltages from 0 V to 10 V. The device features a typical ON-state resistance (ron) of 3 Ω at 5 V, with a maximum propagation delay of 3 ns. It provides 25 MHz bandwidth, -50 dB OFF isolation, and -50 dB crosstalk. The component is housed in a TSSOP-16 package and functions across an operating temperature range of -40°C to +85°C.
Feature Summary
- Utilizes a charge pump mechanism to elevate gate voltage for low and flat ON-state resistance characteristics over the full operating range.
- Supports rail-to-rail switching on data I/O ports with bidirectional data flow capability controlled by select inputs.
- Features low input/output capacitance to minimize capacitive loading and signal distortion on the data bus.
- Includes internal circuitry to prevent damaging current backflow during partial-power-down applications.
Applications
- PCI interface systems
- Memory interleaving architectures
- Bus isolation circuits
Procurement Notes
Verify that the ordering suffix 'PW' corresponds to the TSSOP package and 'R' indicates tape and reel packaging. Confirm RoHS compliance status and lead finish specifications against the latest manufacturer documentation before finalizing procurement orders.
Selection Notes
Select this component when a single-supply 5 V operation is required for high-bandwidth analog or digital switching. Ensure the application demands a 4-bit width with 1-of-2 routing and verify that the 10 V I/O voltage range meets system requirements.
Part Context
This part belongs to the TS5N412 series of high-bandwidth FET bus switches. It is functionally identical to the TS5N412PW but differs in shipping configuration, utilizing tape and reel packaging instead of tubes for automated assembly processes.
Replacement Considerations
The TS5N412DBQR serves as a direct functional replacement using the SSOP package variant.
FAQ
How does the device handle power-down states?
The TS5N412PWR includes Ioff circuitry that prevents damaging current backflow through the device when it is powered down, ensuring isolation during power-off conditions.
What is the maximum data I/O voltage supported?
The device supports a data input/output voltage range from 0 V to 10 V, allowing it to switch signals beyond the VCC supply level.
How is the output-enable pin configured for power-up/down safety?
To ensure a high-impedance state during power up or power down, the OE pin should be tied to VCC through a pullup resistor sized according to the driver's current-sinking capability.
