概述

Description

SN74ALVCH16245DGGR is a 16-bit bidirectional buffer/driver (bus transceiver) with 3-state outputs from TI. It belongs to the ALVCH family and uses low-voltage CMOS with bus-hold on inputs for signal stability. Key features:
- Two 8-bit buses (A0–A7 and B0–B7) with a DIR input to select data flow direction (A↔B) and an OE (output enable, active-low) to tri-state the outputs.
- Single-supply operation from 1.65 V to 3.6 V; suitable for buffering/level-shifting between different voltage domains.
- Input bus-hold and robust ESD protection; designed for high-speed, low-power operation.
- Package: DGGR (28-pin TSSOP), suitable for compact designs.
Applications include buffering and interfacing between microprocessors/FPGA and peripherals, backplane buffering, and general-purpose bidirectional bus buffering. Design note: ensure voltages on both sides stay within Vcc ranges and control DIR and OE to avoid bus contention.

Features

Concise features for SN74ALVCH16245DGGR:
- 16-bit bidirectional bus transceiver (two 8-bit banks)
- Direction control input (DIR) to select A→B or B→A data flow
- Two separate output enable inputs (G1, G2) to tri-state the outputs
- 3-state outputs for bus sharing and isolation
- Operating supply: 1.65 V to 3.6 V (CMOS-compatible I/O)
- High-speed CMOS with low static/dynamic power
- 28-pin DGGR (TSSOP) RoHS-compliant package
- ESD protection; suitable for interfacing microprocessors and memory buses
- Temperature range commonly -40°C to 85°C (industrial) per TI datasheet
(Notes: verify exact temp range for your lot; features may vary slightly by package/revision.)

Package

Package type: 20-pin TSSOP (thin-shrink) package, RoHS‑compliant (lead‑free). DGGR is TI’s package code for this TSSOP‑20 variant.

Pinout

- Pin count: 20 pins (DGGR package)
- Function: 16-bit bidirectional bus transceiver/buffer with tri-state outputs. Data can move in either direction (A↔B) controlled by DIR, with OE enabling/disabling the outputs. Suitable for interfacing two buses or voltage levels.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: TI is an American multinational semiconductor company that designs and manufactures analog, mixed-signal, and digital integrated circuits and related products (processors, memory, power management, etc.).

Application

Typical applications for SN74ALVCH16245DGGR:
- 16-bit bidirectional bus transceiver/buffer with tri-state outputs (DIR and OE)
- Level shifting and buffering between voltage domains (e.g., 3.3V ↔ 5V) on data/address lines
- Buffering/isolation between microcontrollers/FPGA/DSPs and memories or peripherals
- Bus expansion/isolation on backplanes and system interconnects
- Glueless interfaces with bus-hold on inputs for robust, floating-bus operation

Equivalent

Equivalents are other vendors’ 16-bit bidirectional bus transceivers with tri-state outputs (same 1.65–3.6 V range). Examples:
- ON Semiconductor: MC74ALVCH16245, MC74ALVC16245
- NXP/Nexperia: 74ALVCH16245, 74AVCH16245
