7426 Quad Two input NAND, High voltage in Pakistan

This device contains four independent gates each of which performs the logic OR function. The 74LS32 is a 14-Pin Quad 2-Input OR Gate IC. The 74LS32 provides four independent 2-input OR gates with standard push-pull outputs. Featured by Sharvi Electronics The device is designed for operation with a power supply range of 2.0V to 6.0V. Inputs include clamp diodes. This enables the use of current-limiting resistors to interface inputs to voltages in excess of VCC.

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

74HC157 is a high-speed multiplexer integrated circuit consisting of four 2-input digital multiplexers inside the chip. It is pin-compatible with Low-power Schottky TTL. It has two control inputs namely enable and select input. Additionally, it has two groups of registers. The selected input determines the register from which the data comes. Its operation is specified over a temperature range of -55 °C to 125 °C.
