SN54LS540, SN54LS541, SN74LS540, SN74LS541 OCTAL BUFFERS AND LINE DRIVERS WITH 3-STATE OUTPUTS

PRODUCTION DATA documents contain information current as of publicationdate. Products conform to specifications per the terms of Texas Instrumentsstandard warranty. Production processing does not necessarily include testingof all parameters.

features

• 3-State Outputs Drive Bus Lines or Buffer Memory Address Registers
• P-N-P Inputs Reduce D-C Loading
• Hysteresis at Inputs Improves Noise Margins
• Data Flow-thru Pinout (All Inputs on Opposite Side from Outputs)

description

These octal buffers and line drivers are designed to have the performanceof the popular SN54LS240/SN74LS240 series and, at the same time, offer a pinouthaving the inputs and outputs on opposite sides of the package. This arrangementgreatly enhances printed circuit board layout.

The three-state control gate is a 2-input NOR such that if either G1\ or G2\ are high, all eight outputs are in the high-impedancestate.

The 'LS540 offers inverting data and the 'LS541 offers true data at theoutputs.

The SN54LS540 and SN54LS541 are characterized for operation over the fullmilitary temperature range of -55°C to 125°C. The SN74LS540 and SN74LS541are characterized for operation from 0°C to 70°C.
