Product data
CBT3245A
Octal bus switch
2
2003 Jun 27
FEATURES
Standard ’245-type pinout
5 switch connection between two ports
TTL compatible control input levels
Package options include plastic small outline (D), shrink small
outline (DB), thin shrink small outline (TSSOP)
Latch-up protection exceeds 500 mA per JESD78
ESD protection exceeds 2000 V HBM per JESD22-A114,
150 V MM per JESD22-A115 and 1000 V CDM per JESD22-C101
DESCRIPTION
The CBT3245A provides eight bits of high-speed TTL-compatible
bus switching in a standard ’245 device pinout. The low on-state
resistance of the switch allows connections to be made with minimal
propagation delay.
The CBT3245A device is organized as one 8-bit switch. When
enable (OE) is LOW, the 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 two ports.
The CBT3245A is characterized for operation from -40 to +85
°C.
