Quadruple FET bus switch
CBT3125
DESCRIPTION
PIN CONFIGURATION
The CBT3125 quadruple FET bus switch features independent line
switches. Each switch is disabled when the associated Output
Enable (OE) input is HIGH.
FEATURES
• Standard ’125-type pinout (D, DB, and PW packages)
• 5 Ω switch connection between two ports
• TTL-compatible input levels
• Latch-up testing is done to JESDEC Standard JESD78 which

NOTES:
1. Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only,
and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions”
is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
2. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
3. The package thermal impedance is calculated in accordance with JESD 51-7.

On-resistance (Note 3)
NOTES:
1. All typical values are at VCC = 5 V, unless otherwise noted. 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-state resistance is
determined by the lower of the voltages of the two (A or B) terminals.
AC CHARACTERISTICS
Tamb = –40 to +85 °C; CL = 50 pF, unless otherwise noted.

resistance of the switch and a load capacitance of 50 pF, when driven by an ideal voltage source (zero output impedance).
