The SN74CB3T3245 device uses the standard '245-type pinout. The output voltage tracks VCC, allowing for easy down-translation. The device is prime for low-power portable equipment.
Mixed-mode signal operation is supported on all data I/O ports. 5V input down to 3.3V output level shift with 3.3V VCC and 5V/3.3V input down to 2.5V output level shift With 2.5V VCC are possible due to overvoltage tolerant inputs.
This part is friendly to partial power down systems. The I/Os are 5V-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? typical).
The SN74CB3T3245 has both low input and output capacitance minimizes loading (Cio(OFF) = 5pF typical).
Data and control inputs provide undershoot clamp diodes.
The SN74CB3T3245 has low power consumption (ICC = 40μA Maximum).
The SN74CB3T3245 has a VCC operating range from 2.3V to 3.6V.
The data I/Os support 0V to 5V signaling levels (0.8V, 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, 5V).
Control inputs can be driven by TTL or 5V/3.3V CMOS outputs.
