8-BIT PARALLEL-TO-SERIAL SHIFT REGISTER The SN54 , 74LS165 is an 8-bit parallel load or serial-in register with complementary outputs available from the last stage. Parallel inputing occurs asynchronously when the Parallel Load (PL) input is LOW. With PL HIGH, serial shifting occurs on the rising e

DUAL 1-OF-4 DECODER, DEMULTIPLEXER The LSTTL, MSI SN54, 74LS139 is a high speed Dual 1-of-4 Decoder , Demultiplexer. The device has two independent decoders, each accepting two inputs and providing four mutually exclusive active LOW Outputs. Each decoder has an active LOW Enable input which can be

SN54, 74LS122 SN54, 74LS123 RETRIGGERABLE MONOSTABLE MULTIVIBRATORS These dc triggered multivibrators feature pulse width control by three methods. The basic pulse width is programmed by selection of external resistance and capacitance values. The LS122 has an internal timing resistor that allows th

BCD DECADE, MODULO 16 BINARY SYNCHRONOUS BI-DIRECTIONAL COUNTERS The SN54 , 74LS168 and SN54 , 74LS169 are fully synchronous 4-stage up, down counters featuring a preset capability for programmable operation, carry lookahead for easy cascading and a U, D input to control the direction of counting
