7428 Quad Two input NOR in Pakistan

74LS76 comes with dual JK flip-flops. JK flip flops are widely used in daily electronics devices by many methods but the basic operation of the JK flip flop is to store a bit. JK flip flop allows it to store a bit and then allows it to use for further functions. in digital electronics circuits. JK flip flop is one of the popular flip flops due to its clock input, pre-set, and clear functionalities. The JK flip-flop changes its state under the clock pulse signal. The clock signal can be either a positive edge or a negative edge. The clock pulse gives multiple advantages to the flip-flop. 74LS76 also has provided a feature to neglect or prevent invalid outputs.

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 74LS189 is a high-speed 64-bit RAM organized as a 16-word by the 4-bit array. Address inputs are buffered to minimize loading and are fully decoded on-chip. The outputs are 3-state and are in the high impedance state whenever the Chip Select (CS) input is HIGH. The outputs are active only in the read mode and the output data is the complement of the stored data.
