DM74ALS241A - 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.

Key Features

  • s Advanced low power Schottky TTL process oxide-isolated ion-implanted s Functional and pin compatible with the DM74LS counterpart s Improved switching performance with less power dissipation compared with the DM74LS counterpart s Switching response specified into 500Ω and 50 pF load s Switching response specifications guaranteed over full temperature and VCC supply range s PNP input design reduces input loading s Low level drive current: 74ALS = 24 mA Ordering Code: Order Number DM74ALS240AWM.

DM74ALS240A • DM74ALS241A Octal 3-STATE Bus Driver September 1986 Revised February 2000 DM74ALS240A • DM74ALS241A 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 DM74ALS240A control inputs symmetrically enable the respective outputs when set logic LOW, while the DM74ALS241A 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 rampdown.
