SN74ALS541NSR

These octal buffers and line drivers are designed to have the performance of the popular SN54ALS240A/SN74ALS240A series and, at the same time, offer a pinout with inputs and outputs on opposite sides of the package. This arrangement greatly facilitates printed circuit board layout. The 3 - state control gate is a 2 - input NOR gate such that, if either output - enable (OE1 or OE2) input is high, all eight outputs are in the high - impedance state. The SN74ALS540 provides inverted data. The ’ALS541 provide true data at the outputs. The -1 versions of SN74ALS540 and SN74ALS541 are identical to the standard versions, except that the recommended maximum IOL is increased to 48mA. There is no -1 version of the SN54ALS541.

Applications

• Bus driver
• Memory address register buffer

Key features

• Three-state outputs for driving bus lines or buffering memory address registers
• PNP inputs to reduce DC loading
• Pinout arranged along data flow direction, with all inputs on the opposite side of outputs for simplified PCB layout
• Flexible three-state control logic — any output enable line driven high places all outputs in high-impedance state
• Available in both inverting and non-inverting output versions
• -1 suffix version features increased maximum output low-level current for higher load capacity
