description

The SN74CBTS16212 provides 24 bits of

high-speed TTL-compatible bus switching or

exchanging with Schottky diodes on the I/Os to

clamp undershoot. The low on-state resistance of

the switch allows connections to be made with

minimal propagation delay.

The device operates as a 24-bit bus switch or as

a 12-bit bus exchanger that provides data

exchanging between the four signal ports via the

data-select (S0–S2) terminals.
