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. 2 Features and benefits Standard 244-type pinout 5 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 Name Description Version range CBT3244ABQ -40 C to + 85 C DHVQFN20 plastic dual in-line compatible thermal enhanced SOT764-1 very thin quad flat package no leads 20 terminals body 2.5 4.5 0.85 mm CBT3244APW -40 C to + 85 C TSSOP20 plastic thin shrink small outline package 20 leads SOT360-1 body width 4.4 mm CBT3244ADB -40 C to + 85 C SSOP20 plastic shrink small outline package 20 leads SOT339-1 body width 5.3 mm CBT3244AD -40 C to + 85 C SO20 plastic small outline package 20 leads SOT163-1 body width 7.5 mmNexperia CBT3244A Octal bus switch with quad output enables 4 Marking Table 2.Marking codes Type number Marking code CBT3244ABQ CT3244A CBT3244APW CT3244A CBT3244ADB CT3244A CBT3244AD CBT3244AD 5 Functional diagram CBT3244A 1A1 1B1 1A4 1B4 1OE 2A1 2B1 2A4 2B4 2OE 002aab655 Figure 1.Logic diagram CBT3244A All information provided in this document is subject to legal disclaimers.
