Présentation

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.

Pinout

- Pin count: 20 pins (DIP-20/SOIC-20).
- Function: LVCC octal buffer/driver with 3-state outputs (two 4-bit buffers with independent output enables) for low-voltage operation.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: American multinational technology company that designs and manufactures semiconductors and integrated circuits, especially analog and embedded processing ICs.

Application

SN74LVCC3245AN is an octal (8-bit) bus buffer/driver with 3-state outputs used for high-speed, low-power data paths and level shifting. Typical applications:
- Level-shifting and buffering of data/address buses between devices at 2.5–3.3 V logic
- I/O expansion and fan-out between microprocessors/FPGA/ASICs and memory or peripherals
- Bus isolation and backplane interconnects, enabling tri-state sharing on a common bus
- Glueless interfaces in memory, graphics, communications, automotive and industrial equipment
- Portable/embedded systems requiring low power and small package footprint

Package

SN74LVCC3245ANSR comes in a 20-pin Shrink Small-Outline Package (SSOP).
