CBT3244A - Octal bus switch

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.

Features

  • Standard '244-type pinout.
  • 5 Ω switch connection between two ports.
  • TTL compatible control input levels.
  • Latch-up protection exceeds 500 mA per JESD78.
  • ESD protection:.
  • HBM JESD22-A114 exceeds 2000 V.
  • MM JESD22-A115 exceeds 200 V.
  • CDM JESD22-C101 exceeds 1000 V 3 Ordering information Table 1. Ordering information Type number Package Temperature range CBT3244ABQ -40 °C to + 85 °C CBT3244APW CBT3244ADB CBT3244AD -40 °.

CBT3244A Octal bus switch with quad output enables Rev. 3 — 8 September 2017 Product data sheet 1 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 °C to +85 °C.
