74F648SPC规格书详情
General Description
These devices consist of bus transceiver circuits with 3-STATE, D-type flip-flops, and control circuitry arranged for multiplexed transmission of data directly from the input bus or from the internal registers. Data on the A or B bus will be clocked into the registers as the appropriate clock pin goes to a high logic level. Control G and direction pins are provided to control the transceiver function. In the transceiver mode, data present at the high impedance port may be stored in either the A or the B register or in both. The select controls can multiplex stored and real-time (transparent mode) data. The direction control determines which bus will receive data when the enable control G is Active LOW. In the isolation mode (control G HIGH), A data may be stored in the B register and/or B data may be stored in the A register.
Features
■ Independent registers for A and B buses
■ Multiplexed real-time and stored data
■ 74F648 has inverting data paths
■ 74F646/74F646B have non-inverting data paths
■ 74F646B is a faster version of the 74F646
■ 3-STATE outputs
■ 300 mil slim DIP
