HEF4731B; HEF4731V LSI Recommended supply voltage range for HEF4731B is 3 to 15 V and for HEF4731V is 4,5 to 12,5 V. Data are shifted to the next stage on the negative-going transitions of the clock. Low impedance outputs are provided for direct interface to TTL. Fig.2 Pinning diagram. HEF4731BP; HEF4731VP(N): HEF4731BD; HEF4731VD(F): 14-lead DIL; plastic (SOT27-1) 14-lead DIL; ceramic (cerdip) (SOT73) ( ): Package Designator North America FAMILY DATA, IDD LIMITS category LSI Fig.1 Functional diagram. See Family Specifications January 1995 2 Philips Semiconductors Product specification Quadruple 64-bit static shift register HEF4731B; HEF4731V LSI Fig.3 Logic diagram (one of 64-bits shift register). The values given at VDD = 15 V in the following DC and AC characteristics, are not applicable to the HEF4731V, because of its reduced supply voltage range.
