CBT3244A is an octal bus switch with quad output enables. It features a standard '244-type pinout, a 5 Ω switch connection between two ports, TTL compatible control input levels. The package options include plastic small outline (D), shrink small outline (DB), QSOP (DS), and thin shrink small outline (TSSOP). It has latch-up protection exceeding 500 mA per JESD78 and ESD protection exceeding 1000 V HBM per JESD22-A114, 200 V MM per JESD22-A115, and 1000 V CDM per JESD22-C101. The CBT3244A provides eight bits of high-speed TTL-compatible bus switching in a standard '244 device pinout. The low on-state resistance of the switch allows connections to be made with minimal propagation delay. The CBT3244A device is organized as two 4-bit low-impedance switches with separate output-enable (OE) inputs. When OE is LOW, the switch is on and data can flow from port A to port B, or vice versa. When OE is HIGH, the switch is open and high-impedance state exists between the two ports. The CBT3244A is characterized for operation from –40 °C to 85 °C.
The Philips CBT3244A is an octal bus switch with quad output enables designed for high-speed TTL-compatible bus switching. The device is organized as two 4-bit low-impedance switches with separate output-enable inputs, allowing data to flow between two ports or enter a high-impedance state.
