JAJSFK0C October 2003 – May 2018 SN74CB3T3245
The SN74CB3T3245 device uses the standard '245-type pinout. The output voltage tracks VCC, allowing for easy down-translation. The device is ideal for low-power portable equipment.
Mixed-mode signal operation is supported on all data I/O ports. 5-V input down to 3.3-V output level shift with 3.3-V VCC and 5-V/3.3-V input down to 2.5-V output level shift With 2.5-V VCC are possible due to overvoltage tolerant inputs.
This part is friendly to partial power down systems. The I/Os are 5-V-tolerant with the device powered up or powered down and Ioff supports partial-power-down mode operation
The SN74CB3T3245 has a bidirectional data flow with near-zero propagation delay.
The SN74CB3T3245 has low ON-state resistance (ron) characteristics (ron = 5 Ω Typical)
The SN74CB3T3245 has both low input and output capacitance minimizes loading (Cio(OFF) = 5 pF Typical)
Data and control inputs provide undershoot clamp diodes.
The SN74CB3T3245 has low power consumption (ICC = 40 μA Maximum)
The SN74CB3T3245 has a VCC operating range from 2.3 V to 3.6 V.
The data I/Os support 0- to 5-V signaling levels (0.8-V, 1.2-V, 1.5-V, 1.8-V, 2.5-V, 3.3-V, 5-V)
Control inputs can be driven by TTL or 5-V/3.3-V CMOS outputs
