N-Bit 1 of 8 Decoder
Features: • Provides direct control of up to
7 input and 7 output devices • CHIP ENABLE (CE) allows easy
expansion for multi-level I/O systems
The RCA-CDP1853 and CDP1853C are 1 of 8 decoders designed for use in general purpose microprocessor systems. These devices, which are functionally identical, are specifically designed for use as gated N-bit decoders and interface directly with the 1800-series microprocessors without additional components. The CDP1853 has a recommended operating voltage range of 4 to 10.5 volts, and the CDP1853C has a recommended operatinQ voltage range of 4 to 6.5 volts.
When CHIP ENABLE (CE) is high, the selected output will be true (high) from the trailing edge of CLOCK A (high-tolow transition) to the trai.
