規格內容說明 |
These octal buffers and line drivers are designed to have the performance of the popular SN54LS240/SN74LS240 series and, at the same time, offer a pinout having the inputs and outputs on opposite sides of the package. This arrangement greatly en hances printed circuit board layout.
The three-state control gate is a 2-input NOR such that if either G 1 or G2 are high,all eight outputs JaTre in the high-impedance state.
The 'LS540 offers inverting data and the 'LS541 offers true data at the outputs.
The SN54 LS540 and SN54 LS541 are characterized for operation over the full military temperature range of -55 C to 125 C. The SN74LS540 and SN74LS541 are characterized for operation from OC to 70 C.
FEATURES:
■3-State Outputs Drive Bus Li nes or
■Buffer Memory Address Registers
■P-N-P Inputs Reduce D-C Loading
■Hγsteresis at Inputs Improves Noise Margins
■Data Flow-thru Pinout (AII Inputs on Opposite Side from Outputs)
