What are the key features of SN74AHC16541DLG4?

  • 16-bit octal buffer with dual active-low output enable (OE) signals for flexible bus control
  • AHC-family CMOS logic with 3.3 V supply voltage and 50 pF load capacitance rating
  • Low-power 48-pin SSOP green package (SSOP-48) with RoHS-compliant e4 solder specification

What is SN74AHC16541DLG4 used for?

The SN74AHC16541DLG4 is ideal for high-density bus-interface designs in embedded systems, industrial controllers, and telecommunications equipment where 16-bit wide data paths must be driven with individual output-enable control. Its AHC-family low-power CMOS technology makes it suitable for battery-powered portable devices and power-sensitive server backplane applications requiring 3.3 V logic levels. The dual unidirectional output enables allow designers to partition 16-bit buses into two independently gated 8-bit segments, supporting complex memory expansion and data routing architectures.

Frequently Asked Questions

What supply voltage does SN74AHC16541DLG4 require and what load capacitance is it rated for?

SN74AHC16541DLG4 operates from a 3.3 V supply rail and is characterized with a 50 pF load capacitance (CL). The AHC logic family supports a nominal VCC range of 2 V to 5.5 V, giving designers flexibility across multiple system voltage standards while meeting timing specifications at the rated 50 pF load.

How does the dual output-enable architecture of SN74AHC16541DLG4 benefit wide bus designs?

SN74AHC16541DLG4 provides two separate active-low output enable inputs, each controlling 8 of the 16 output bits. This allows a single 48-pin device to manage two independent 8-bit bus segments simultaneously, reducing component count and board space compared to using two discrete 8-bit buffer ICs in a 3.3 V system.

Which board-level package does SN74AHC16541DLG4 use and how many signal pins does it provide?

The part uses a 48-pin SSOP (Small Shrink Outline Package) with 0.635 mm pitch, providing 16 data inputs, 16 data outputs, 2 output enable pins, and required power and ground pins. The SSOP-48 footprint offers a compact PCB area while remaining compatible with standard reflow soldering at MSL-rated temperatures.
