DS8216D 4-Bit Bidirectional Bus Driver IC DIP-16
DS8216D 4-Bit Bidirectional Bus Driver IC DIP-16 is a high-performance 4-bit bidirectional bus transceiver designed for bus-oriented digital systems. It features four TRI-STATE bidirectional data buffers, TTL-compatible inputs and outputs, and high-current drive capability for reliable interfacing with memories, I/O devices, and microprocessors. The device supports bidirectional data transfer controlled by the DIEN input and device enable via the CS input. With low input loading, fast propagation delay, and compatibility with 8080-type CPUs, it is ideal for data bus buffering, interface control, and digital communication applications. The DS8216D corresponds to the non-inverting DP8216 family described in the uploaded datasheet.
