Technical Details & Description

16-VSSOP multiplexer for 1.65V to 3.6V signal routing

The TC7MBL3257CFK(EL) is a single-supply 4 x 2:1 multiplexer/demultiplexer from Toshiba's TC7MB series, packaged in a 16-VSSOP (0.118" body width, 3.00mm wide VFSOP footprint).

Supply voltage and signal integrity considerations

The single supply rail from 1.65V to 3.6V means the mux passes signals at the same voltage as the supply — no dual-rail level translation. The 4 x 2:1 configuration routes one of two input channels to a common output per section, with the independent circuit count of 1 meaning all four sections share the same select and enable logic.

Active lifecycle status with ROHS3 compliance — the part is manufactured by Toshiba Semiconductor and available through distribution. Sourced to order against an RFQ; current pricing and lead time confirmed at quote time.

Frequently asked questions

Will TC7MBL3257CFK(EL) drop into a board designed for TC7MBL3253CFK(EL)?

No — the TC7MBL3253CFK(EL) is a 2 x 4:1 multiplexer/demultiplexer, while the TC7MBL3257CFK(EL) is a 4 x 2:1 configuration. The circuit topology differs, so a direct drop-in replacement without rewiring the board is not possible.

What compliance documentation does Toshiba provide for TC7MBL3257CFK(EL)?

The part is ROHS3 compliant per the lifecycle record. Standard Toshiba documentation includes the datasheet and ROHS declaration. No UL or IEC certification is listed for this device.
