The 74LVCH162245APAG is a non-inverting transceiver from IDT, designed for bidirectional data transfer in 2.7V to 3.6V systems. It features 2 channels with 3-State outputs, offering 12mA drive on one side and 24mA on the other. This makes it ideal for bus interfacing, level shifting, and memory data isolation. The 48-TFSOP package is compact and suitable for high-density PCBs. Its low power consumption and high-speed operation make it a reliable choice for modern digital systems.
- Bidirectional Data Flow: Allows data transfer in both directions, reducing component count.
- Asymmetric Drive (12mA/24mA): Provides flexibility for connecting different logic families.
- 3-State Outputs: Enables bus sharing and prevents contention.
- Low Power 74LVCH Family: Suitable for power-sensitive applications.
Bidirectional Bus Transceiver
Use the 74LVCH162245APAG to connect two data buses that need to communicate in both directions, such as between a CPU and a peripheral chip.
Level Shifting with Direction Control
In mixed-voltage systems, this transceiver can shift signals between 2.7V and 3.6V domains while providing direction control via the DIR pin.
Memory Data Bus Isolation
In memory systems, this transceiver can isolate the memory data bus from the controller when not in use, reducing capacitive loading.
