CBT3244
FEATURES
DESCRIPTION
The CBT3244 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.
• Standard ’244-type pinout
• 5 Ω switch connection between two ports
• TTL compatible control input levels
The CBT3244 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.
• Package options include plastic small outline (D), shrink small
outline (DB), thin shrink small outline (TSSOP)
• Latch-up protection exceeds 500 mA per JESD78
• ESD protection exceeds 2000 V HBM per JESD22-A114,
The CBT3244 is characterized for operation from –40 to 85 °C.
200 V MM per JESD22-A115 and 1000 V CDM per JESD22-C101

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.
