2 / 8 page Philips Semiconductors Product data CBT16211 24-bit bus switch with 12-bit output enables 2 2001 Jun 13 853-2259 26502 FEATURES • 5 Ω switch connection between two ports • TTL compatible control input levels • Package options include plastic shrink small outline (SSOP), thin shrink small outline (TSSOP) • ESD protection exceeds 1000 V CDM per JESD22-C101 • Latch-up testing is done to JESDEC Standard JESD78 which exceeds 100 mA 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.
