General Description

OF ”B” SERIES CMOS DEVICES” BEY (Plastic Package) BF (Ceramic Frit Seal Package) BM1 (Micro Package) ORDER CODES : HCC40208BF HCF40208BEY HCF40208BM1 PIN CONNECTIONS DESCRIPTION The HCC40208B (extended temperature range) and HCF40208B (intermediate temperature range) are monolithic integrated circuits, available in 24-lead dual in-line plastic or ceramic package and plastic micro package.

The HCC/HCF40208B is a 4 x 4 multiport register containing four 4-bit registers, write address decoder, two separate read address decoders, and two 3-state output buses.

When the ENABLE input is low, the corresponding output bus is switched, independently of the clock to a high-impedance state.
