CBT3244A
Datasheet
General description
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 Cel to +85 Cel.
Features
- Standard '244-type pinout
- 5 Ohm switch connection between two ports
- TTL compatible control input levels
- Package options include:
- plastic small outline (SO20)
- shrink small outline (SSOP20)
- shrink small outline, QSOP (SSOP20)
- thin shrink small outline (TSSOP20)
- depopulated heatsink very thin quad flat package, no leads (DHVQFN20)
- Latch-up protection exceeds 500 mA per JESD78
- ESD protection exceeds 2000 V HBM per JESD22-A114, 200 V MM per JESD22-A115 and 1000 V CDM per JESD22-C101
