Product data sheet
1. General description
The CBT3126 is a quadruple FET bus switch features independent line switches. Each
switch is disabled when the associated Output Enable (OE) input is LOW.
The CBT3126 is characterized for operation from −40 °C to +85 °C.
2. Features
I Standard ’126-type pinout
I Multiple package options
I 5 Ω switch connection between two ports
I TTL-compatible input levels
I Minimal propagation delay through the switch
I Latch-up protection exceeds 500 mA per JEDEC standard JESD78 class II level A
I ESD protection:
N HBM JESD22-A114E exceeds 2000 V
N MM JESD22-A115-A exceeds 200 V
N CDM JESD22-C101C exceeds 1000 V
I Specified from −40 °C to +85 °C

[1] All typical values are measured at VCC = 5 V; Tamb = 25 °C.
[2] This is the increase in supply current for each input that is at the specified TTL voltage level rather than VCC or GND.
[3] Measured by the voltage drop between the A and the B terminals at the indicated current through the switch. ON resistance is
determined by the lowest voltage of the two (A or B) terminals.
