Product data
24-bit bus exchange switch with 12-bit output enables
CBT16212
FEATURES
•
5
Ω
switch connection between two ports
•
TTL compatible control input levels
•
Latch-up testing is done to JEDEC Standard JESD78 which
exceeds 100 mA
DESCRIPTION
The CBT16212 provides 24 bits of high-speed TTL-compatible bus
switching or exchanging. The low on-state resistance of the switch
allows connections to be made with minimal propagation delay.
The CBT16212 operates as 24-bit bus switch or a 12-bit bus
exchanger, which provides data exchanging between the four signal
ports via the data-select (S0–S2) terminals.
The CBT16212 is characterized for operation from –40 to +85°C.
•
ESD protection exceeds 1500 V HBM per JESD22-A114 and
1000 V CDM per JESD22-C101
