SN74CB3T3257 Datasheet 4-bit 1-of-2 Fet Multiplexer/demultiplexer

Manufacturer: Texas Instruments

Overview: www.ti.com SN74CB3T3257 4-BIT 1-OF-2 FET MULTIPLEXER/DEMULTIPLEXER 2.5-V/3.

General Description

/ORDERING INFORMATION The SN74CB3T3257 is a high-speed TTL-compatible FET multiplexer/demultiplexer with low ON-state resistance (ron), allowing for minimal propagation delay.

The device fully supports mixed-mode signal operation on all data I/O ports by providing voltage translation that tracks VCC.

The SN74CB3T3257 supports systems using 5-V TTL, 3.3-V LVTTL, and 2.5-V CMOS switching standards, as well as user-defined switching levels (see Figure 1).

Key Features
