General description The CBT3257A is a quad 1-of-2 high-speed TTL-compatible multiplexer/demultiplexer. The low ON-state resistance of the switch allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise. Output enable (OE) and select-control (S) inputs select the appropriate nB1 and nB2 outputs for the nA input data. The CBT3257A is characterized for operation from −40 °C to +85 °C. 2. Features s 5 Ω switch connection between two ports s TTL-compatible input levels s Minimal propagation delay through the switch s ESD protection exceeds 2000 V HBM per JESD22-A114, 200 V MM per JESD22-A115 and 1000 V CDM per JESD22-C101 s Latch-up testing is done to JEDEC standard JESD78 which exceeds 100 mA 3.

[3] Measured by the voltage drop between the A and the B terminals at the indicated current through the switch. ON-state resistance is determined by the lowest voltage of the two (A or B) terminals. 10.

The propagation delay is based on the RC time constant of the typical ON-state resistance of the switch and a load capacitance, when driven by an ideal voltage source (zero output impedance).
