The MC14099B is an 8-bit addressable latch. Data is entered in serial form when the appropriate latch is addressed (via address pins A0, A1, A2) and write disable is in the low state. For the MC14099B the input is a unidirectional write only port. The data is presented in parallel at the output of the eight latches independently of the state of Write Disable, Write/Read or Chip Enable. A Master Reset capability is available on both parts.
The MC14099B is an 8‑bit addressable latch with serial data input and parallel output. Data is entered serially when the latch is addressed via pins A0, A1, A2, and the device features a master reset and write‑disable function. The part operates over a wide supply range and can drive low‑power TTL loads.
The datasheet includes detailed pin assignments, electrical and switching characteristics, timing diagrams, and mechanical package dimensions for PDIP‑16 and SOIC‑16 variants. Ordering information, maximum ratings, and packaging details are also provided.
