2 / 12 page Philips Semiconductors Product data CBT3245A Octal bus switch 2 2003 Jun 27 FEATURES • Standard ’245-type pinout • 5 Ω 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.
