24-bit bus switch with 12-bit output enables
CBT16211
FEATURES
* 5 switch connection between two ports * TTL compatible control input levels * Package options include plastic shrink small outline (SSOP),
thin shrink small outline (TSSOP)
DESCRIPTION
The CBT16211 provides 24 bits of high-speed TTL-compatible bus switching. The low on-state resistance of the switch allows connections to be made with minimal propagation delay. The device is organized as a dual 12-bit bus switch with separate output-enable (OE) inputs. It can be used as two 12-bit bus switches or as one 24-bit bus switch. When OE is low, the associated 12-bit bus switch is on, and port A is connected to port B. When OE is high, the switch is open, and a high-impedance state exists between the ports. The CBT16211 is characterized for operation from -40 to 85 C.
* ESD protection exceeds 1000 V CDM per JESD22-C101 * Latch-up testing is done to JESDEC Standard JESD78 which
exceeds 100 mA

Tstg Storage temperature range -65 to 150 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.

NOTES: 1. All typical values are at VCC = 5 V, Tamb = 25 C. 2. This is the increase in supply current for each input that is at the specified TTL voltage level rather than VCC or GND. 3. Measured by the voltage drop between the A and the B terminals at the indicated current through the switch. On-state resistance is determined by the lowest voltage of the two (A or B) terminals.
