Description
The SN74LVCC3245ANSR is TI’s low‑voltage CMOS device in the SN74LVCC family. It functions as a bidirectional bus buffer/transceiver with tri‐state outputs, allowing two buses to communicate through a pair of data paths. Controlled by a directional input (DIR) and an output‑enable input (OE), its outputs go high‑impedance when disabled. It operates on a low voltage supply (typically 1.65 V to 3.6 V) and accepts standard CMOS/TTL levels, suitable for level shifting and buffering in mixed‑voltage systems. The device comes in a 20‑pin package (SOP/TSSOP) and is RoHS compliant (suffix SR). Typical uses include interfacing microprocessors/microcontrollers to memory or peripherals, backplane buffering, and other glue‑logic tasks where bidirectional data transfer and bus sharing are needed. For exact electrical specs, timing, and packaging details, consult the TI datasheet.
