Description
Apr 1, 1987 ( 74LS251 ) in Figure 1. During each ST-BUS channel period the mux selects one bit from each output stream, beginning with stream 0 (STo0). multiplexers such as the 74LS153 or 74LS251 may also be used, but some additional circuitry will be required to convert the digit output to TTL compatible logic 4-bit binary full adder w/fast carry. $0.57. D. IC444. 74LS251 . Data selectors/ multiplexers tri-state. $0.61. D. IC445. 74LS195. 4-bit parallel access shift register .
