CBT3244A
Octal bus switch with quad output enables
Rev. 3 — 8 September 2017

Product data sheet
General description
The CBT3244A provides eight bits of high-speed TTL-compatible bus switching in
a standard '244 device pinout. The low ON-state resistance of the switch allows
connections to be made with minimal propagation delay.
The CBT3244A device is organized as two 4-bit low-impedance switches with separate
output-enable (OE) inputs. When OE is LOW, the switch is on and data can flow from
port A to port B, or vice versa. When OE is HIGH, the switch is open and high-impedance
state exists between the two ports.
The CBT3244A is characterized for operation from -40 °C to +85 °C.

(1) This is not a supply pin, the substrate is attached to
this pad using conductive die attach material. There is no
electrical or mechanical requirement to solder this pad
however if it is soldered the solder land should remain
floating or be connected to GND.

The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction temperatures which
are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150 °C.
The input and output voltage ratings may be exceeded if the input and output current ratings are observed.

All typical values are measured at VCC = 5 V; Tamb = 25 °C.
This is the increase in supply current for each input that is at the specified TTL voltage level rather than VCC or GND.
Measured by the voltage level 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.

This parameter is warranted but not production tested. The propagation delay is based on the RC time constant of the typical ON-state resistance of the
switch and a load capacitance of 50 pF, when driven by an ideal voltage source (zero output impedance).
tpd is the same as tPHL and tPLH.
ten is the same as tPZH and tPZL.
