STMicroelectronics HCF40194B
The HCC40104B, HCC40194B, (extended temperature range) and the HCC40104B, HCF40194B (intermediate temperature range) are monolithic integrated circuits, available in 16-lead dual in-line plastic or ceramic package and plastic micro package. The HCC/HCF 40104B is a universal shift register featuring parallel inputs, parallel outputs, SHIFT RIGHT and SHIFT LEFT serial inputs, and a high-impedance third output state allowing the device to be used in bus-organized systems.

DESCRIPTION
OF ”B” SERIES CMOS DEVICES” EY (Plastic Package) F (Ceramic Package) C1 (Plastic Chip Carrier ) ORDER CODES : HCC401XXBF HCF401XXBEY HCF401XXBC1 DESCRIPTION
In the parallel-load mode (S0 and S1 are high), data is loaded into the associated flip-flop and appears at the output after the positive transition of the CLOCK input. During loading, serial data flow is inhibited. Shift-right and shift-left are accomplished synchronously on the positive clock edge with serial data entered at the SHIFT RIGHT and SHIFT LEFT serial inputs, respectively. Clearing the register is accomplished by setting both mode controls low and clocking the register. When the output enable input is low, all outputs assume the high impedance state. The HCC/HCF40194B is a universal shift register featuring parallel inputs, parallel outputs SHIFT RIGHT and SHIFT LEFT serial inputs, and a direct overriding clear input. In the parallel-load mode (S0 and S1 are high), data is loaded into the associated flip-flop and June 1989 PIN CONNECTIONS 40104B 40194B 1/12 HCC/HCF40104B/40194B appears at the output after the positive transition of the CLOCK input.
