CBT3253A
Dual 1-of-4 FET multiplexer/demultiplexer
Rev. 4 — 31 October 2014
Product data sheet
1. General description
The CBT3253A is a dual 1-of-4 high-speed TTL-compatible FET
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.
When the output enable input (nOE) is LOW, the 1-of-4 multiplexer/demultiplexer is
enabled. The data path is selected by the select control inputs (S0, S1). When nOE is
HIGH, the 1-of-4 multiplexer/demultiplexer is disabled. The switch terminals are in the
high impedance OFF-state, independent of S0 and S1.
The CBT3253A is characterized for operation from 40 C to +85 C.
2. Features and benefits

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. The lowest voltage of the
two (A or B) terminals determines the ON resistance.

This parameter is warranted but not production tested. The propagation delay is based on the RC time constant of the typical ON
resistance of the switch and a load capacitance, when driven by an ideal voltage source (zero output impedance).

tPLH and tPHL are the same as tpd.
tPZL and tPZH are the same as ten.
tPLZ and tPHZ are the same as tdis.
