• Ideal for Low-Power Portable Equipment
The SN74CB3T16212 is a high-speed TTL-compatible FET bus-exchange switch, with low ON-state resistance
(r
on
), 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 V
CC
. The SN74CB3T16212 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).
