概述

Description

NLV74VHC244DTR2G is an 8-bit buffer/line driver (74VHC family) with 3-state outputs. It contains two 4-bit buffer sections (A0–A7 inputs to Y0–Y7 outputs) and two active-low enable pins (G1 and G2) controlling each group. When an enable is low, the corresponding four buffers pass A to Y; when high, those outputs go high-impedance. It’s used to buffer/partition buses in low-voltage digital designs. The “NLV” indicates the low-voltage variant, and “DTR2G” denotes package/packaging (tape-and-reel, RoHS-compliant). For exact supply voltage range, input thresholds, timing specs, and packaging details, see the manufacturer’s datasheet.

Features

- Octal buffer/line driver (8-bit) with 3-state outputs
- Dual 4-bit buffers (two enable pins: OE1 and OE2) with independent control
- Non-inverting operation
- Active-low output enables; outputs go high-impedance when disabled
- Suitable for low-voltage CMOS applications; typically Vcc in the NLV range (1.65 V–3.6 V)
- Ioff support (partial-power-down immunity) and standard CMOS/TTL-compatible inputs
- ESD protection and general purpose high-speed buffering
- Package: DTR2G (tape-and-reel) variant
Note: exact voltage range and temp range depend on the specific device revision; refer to the datasheet for precise specifications.

Package

20-pin DTR package (TSSOP-20), RoHS-compliant.

Pinout

- Pin count: 20 pins (SOIC/TSSOP 20-pin package).
- Function: Octal buffer/line driver with 3-state outputs (two 4-bit buffers). Non-inverting data path from A1–A8 to Y1–Y8 with two active-low enable inputs (1OE and 2OE) to tri-state the corresponding outputs. Power pins Vcc and GND included.

Manufacturer

Manufacturer: Nexperia. It is a global semiconductor company (formerly part of NXP Semiconductors) that designs and manufactures discrete devices and logic ICs, such as buffers/drivers (74VHC series), MOSFETs, protection devices, for automotive, industrial, and consumer electronics.

Application

NLV74VHC244DTR2G is an octal buffer/line driver with 3-state outputs. Applications include:
- Buffering/driving 8-bit data and address buses
- Bus sharing/isolation between MCU/FPGA/memory
- Level shifting between 3.3V and 5V logic domains
- Reducing host load and preventing bus contention
- Signal conditioning in high-speed digital circuits
- Backplanes and general-purpose I/O buffering in embedded systems

Equivalent

Equivalent products are other vendors’ 74VHC244 octal buffer/line drivers (3-state outputs). Examples:
- TI SN74VHC244 (D/related variants)
- NXP/Nexperia 74VHC244
- STMicroelectronics 74VHC244
- Renesas M74VHC244
- On Semiconductor MC74VHC244
Any 74VHC244 device from these manufacturers (same speed grade and voltage range) is generally cross‑compatible, noting packaging/speed differences.
