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

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.

74LS02 74AHS02 7402 Quad 2-input NOR gate in Pakistan

Each counter has a divide-by-two section and either a divide-by-five (LS90), divide-by-six (LS92) or divide-by-eight (LS93) section which are triggered by a HIGH-to-LOW transition on the clock inputs. Each section can be used separately or tied together (Q to CP) to form BCD, bi-quinary, modulo-12, or modulo-16 counters. All of the counters have a 2-input gated Master Reset (Clear), and the LS90 also has a 2-input gated Master Set (Preset 9).
