SN74CB3T3257 Product details

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).TA 40°C to 85°C TSSOP P
