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.

NOTES:

1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability .

2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction
temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150°C.

3. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
