Overview

Description

The 74HC4049D is a hex non-inverting buffer/driver in the 74HC CMOS family. It contains six independent buffers with high input impedance and outputs that drive other CMOS inputs or small loads. There are no enable pins; all six buffers are always active, providing straightforward buffering and fan-out.
Key points:
- Six non-inverting buffers (no inversion, no tri-state)
- Vcc range typically 2–6 V (commonly used at 5 V)
- High input impedance; moderate output drive to drive multiple CMOS inputs or light loads
- Package variant denoted by “D” (e.g., SOIC)
Typical uses:
- Buffering and isolating signals between stages
- Increasing fan-out
- Simple level buffering within a single supply (not ideal for wide 3.3 V ↔ 5 V translation without checking thresholds)
Notes:
- Inputs should stay within 0 to Vcc. Thresholds scale with Vcc, so check that your source voltages are recognized as valid logic levels at your chosen Vcc. For level shifting beyond simple buffering, consider dedicated translators.

Features

Concise features of 74HC4049D:
- Hex buffer/driver: six non-inverting buffers in one package
- Wide supply: 2V to 6V operating range
- High-impedance inputs; rail-to-rail CMOS outputs
- High drive capacity for multiple inputs (large fan-out)
- Low static and dynamic power consumption
- Fast switching speeds (typical propagation delays in the tens of ns, depending on load and Vcc)
- Robust noise margins and ESD protection
- Packages: DIP-14 and surface-mount (D suffix variants)
- Temperature variants available (commercial/industrial, depending on device)
These summarize the core features; consult the specific datasheet for exact electrical specs and package options.

Package

The 74HC4049D is a 14‑pin device, typically in the SOIC‑14 (surface‑mount, D suffix) package; DIP‑14 versions are also commonly available from some vendors.

Pinout

- Pin count: 14 pins (DIP-14/SOIC-14; suffix D denotes these package types).
- Function: Hex non-inverting buffer/driver (six buffers with high input impedance, used to buffer and drive loads). Each buffer provides a separate input/output; Vcc and GND present on device.

Manufacturer

There isn’t a single exclusive manufacturer for the 74HC4049D. It’s a standard 74HC logic device produced by many vendors, for example:
- Texas Instruments (TI)
- NXP Semiconductors
- STMicroelectronics
- ON Semiconductor
- Renesas
- Diodes Incorporated
Kind of company: These are global semiconductor companies that design and manufacture integrated circuits and other electronic components.

Application

Applications of 74HC4049D:
- Hex non‑inverting buffer/driver for level shifting between voltage domains (e.g., 3.3V and 5V)
- Buffering and fan-out to multiple CMOS/TTL inputs
- Clock/data distribution with clean edges
- Isolation and noise reduction between noisy sources and receivers
- Driving higher-capacitance loads and long lines
- Simple digital buffering in mixed-voltage interfaces

Equivalent

Equivalent devices (hex buffer/driver, non-inverting) to 74HC4049D include:
- SN74HC4049D (TI, same family)
- SN74HCT4049D (TTL-compatible inputs, TI)
- CD4049UBE / CD4049BE (4000-series CMOS)
- MC4049UB (Motorola/ON Semiconductor)
Note: check voltage range, thresholds, and drive in datasheets, as these parts differ in Vcc range and fan-out despite similar function.
