74HC74 7474 IC Dual D-type Flip-flop IC in Pakistan

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.

The 74LS138 is a 3:8 Decoder IC that is commonly used in decoding or de-multiplexing circuits for memory decoding or data routing purposes. It is designed for high-speed operations and has three enable pins to make it easier to cascade with other ICs. The device decodes 1-of-8 lines, set by x3 binary select inputs & three enable inputs. The LS138 can be used as an 8- output demultiplexer by using one active LOW Enable input as data input & the other Enable inputs as strobes. The IC has an operating voltage from 1.0V to 5.5V with a low power consumption of 32mW. The propagation delay is around 21nS.

The 74LS160 IC package, consisting of 16 pins, contains a single 4 bit synchronous counter circuit which can be wired for decade counting mod, without external logic chips. By wiring more than one 74LS160 together (cascading), it is possible to make higher count lengths (powers of ten). For example, two 74LS160s cascaded together would yield a counter capable of decimally counting the range 00 – 99.
