7406 Hex Inverter, High voltage Open collector 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.

The 7404 is a triple-buffered inverter. It has high noise immunity and the ability to drive 10 LS-TTL loads. The 74HC logic family is functionally as well as pin-out compatible with the standard 74LS logic family. All inputs are protected from damage due to static discharge by internal diode clamps to VCC and ground.

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.
