74LS139 Dual 1-of-4 Decoder/ Demultiplexer in Pakistan

7475 74LS75 4-BIT BISTABLE LATCHES in Pakistan

This Data Selector/Multiplexer contains full on-chip decoding to select one-of-eight data sources as a result of a unique three-bit binary code at the Select inputs. Two complementary outputs provide both inverting and non-inverting buffer operation. A Strobe input is provided which, when at the high level, disables all data inputs and forces the Y output to the low state and the W output to the high state. The Select input buffers incorporate internal overlap features to ensure that select input changes do not cause invalid output transients. RoboticsBD

The NAND GATES IC 74HC00 Nand IC 7400 74LS00 provides four independent 2-input NAND gates with standard push-pull outputs. The device is designed for operation with a power supply range of 2.0V to 6.0V.
