74ALS240A-1 - Octal 3-STATE Bus Driver

Download the 74ALS240A-1 datasheet PDF. This datasheet also covers the 74ALS240A variant, as both devices belong to the same octal 3-state bus driver family and are provided as variant models within a single manufacturer datasheet.

General Description

These octal 3-STATE bus drivers are designed to provide the designer with flexibility in implementing a bus interface with memory, microprocessor, or communication systems.

The output 3-STATE gating control is organized into two separate groups of four buffers.

Key Features

  • the same performance as the standard version with the addition of increased current drive capability to meet the current requirements of various bus architectures. F.

DM74ALS240A/DM74ALS241A/74ALS240A-1 Octal 3-STATE Bus Driver February 1998 DM74ALS240A/DM74ALS241A/74ALS240A-1 Octal 3-STATE Bus Driver General Description These octal 3-STATE bus drivers are designed to provide the designer with flexibility in implementing a bus interface with memory, microprocessor, or communication systems. The output 3-STATE gating control is organized into two separate groups of four buffers. The ’ALS240A control inputs symmetrically enable the respective outputs when set logic low, while the ’ALS241A has complementary enable gating. The 3-STATE circuitry contains a feature that maintains the buffer outputs in 3-STATE (high impedance state) during power supply ramp-up or ramp-down. This eliminates bus glitching problems that arise during power-up and power-down.
