FEATURES
CBT3244A
PIN CONFIGURATION — SO, SSOP, QSOP, and
TSSOP
• Standard ’244-type pinout
• 5 Ω switch connection between two ports
• TTL compatible control input levels
• Package options include plastic small outline (D), shrink small
outline (DB), QSOP (DS), and thin shrink small outline (TSSOP)
• Latch-up protection exceeds 500 mA per JESD78
• ESD protection exceeds 1000 V HBM per JESD22-A114,
200 V MM per JESD22-A115 and 1000 V CDM per JESD22-C101
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.

NOTES:
1. Stresses beyond those listed 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 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.
3. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.

NOTES:
1. All typical values are 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-state resistance is determined by the lowest voltage of the two (A or B) terminals.

NOTE:
1. 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).
