CBT3257A-Q100

Quad 1-of-2 multiplexer/demultiplexer

Rev. 1 — 28 November 2019

Product data sheet

1. General description

The CBT3257A-Q100 is a quad 1-of-2 high-speed TTL-compatible multiplexer/demultiplexer.

The low ON 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.

This product has been qualified to the Automotive Electronics Council (AEC) standard Q100

(Grade 1) and is suitable for use in automotive applications.

2. Features and benefits

•

Automotive product qualification in accordance with AEC-Q100 (Grade 1)

Specified from -40 °C to +85 °C and from -40 °C to +125 °C

•

5 Ω switch connection between two ports

TTL-compatible input levels

Minimal propagation delay through the switch

Latch-up protection exceeds 100 mA per JEDEC standard JESD78 class II level A

ESD protection:

•

MIL-STD-883, method 3015 exceeds 2000 V

HBM JESD22-A114F exceeds 2000 V

MM JESD22-A115B exceeds 200 V (C = 200 pF, R = 0 Ω)

[1] All typical values are measured at V_CC= 5 V; T_amb= 25 °C.

[2] This is the increase in supply current for each input that is at the specified TTL voltage level rather than V_CCor GND.

[3] Measured by the voltage drop between the nA and the nBn terminals at the indicated current through the switch. The lowest voltage of

the two (nA or nBn) terminals determines the ON resistance.
