HCF4094 8-stage shift and store bus register with 3-stage outputs Datasheet - production data Applications Automotive Industrial SO-16 Computer Consumer Features 3- state parallel outputs for connection to Description common bus The HCF4094 is a monolithic integrated circuit Separate serial outputs synchronous to both fabricated in metal oxide semiconductor positive and negative clock edges for technology available in an SO-16 package. The cascading HCF4094 is an 8-stage, serial shift register having Medium speed operation 5 MHz at 10 V a storage latch associated with each stage for strobing data from the serial input to parallel Quiescent current specified up to 20 V buffered 3-state outputs. The parallel outputs may Standardized symmetrical output be connected directly to common bus lines. Data characteristics are shifted on positive clock transition. The data in 5 V, 10 V, and 15 V parametric ratings each shift register stage are transferred to the storage register when the STROBE input is high. Input leakage current I = 100 nA (max.) at I Data in the storage register appear at the outputs V = 18 V, T = 25 C DD A whenever the OUTPUT-ENABLE signal is high. 100% tested for quiescent current Two serial outputs are available for cascading a ESD performance number of HCF4094 devices. Data are available at the Q serial output terminal on positive clock HBM: 1 kV S edges to allow for high speed operation in a MM: 200 V cascaded system in which the clock rise time is CDM: 1 kV fast. The same serial information, available at the Q terminal on the next negative clock edge, S provides a means for cascading HCF4094 devices when the clock rise time is slow. Table 1.
