Philips Semiconductors Product data

CBT1621224-bit bus exchange switch with 12-bit output enables

FEA TURES

•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

•ESD protection exceeds 1500 V HBM per JESD22-A114 and

1000 V CDM per JESD22-C101

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.
