Part Description: 74F646 Octal Transceiver Register with 3-STATE Outputs

Part Details:

74F646 O March 1988 Revised January 2004 cta 74F646 l Tr Octal Transceiver/Register with 3-STATE Outputs anscei General Description Features These devices consist of bus transceiver circuits with s Independent registers for A and B buses ver/ 3-STATE, D-type flip-flops, and control circuitry arranged s Multiplexed real-time and stored data for multiplexed transmission of data directly from the input s 74F646 has non-inverting data paths R bus or from the internal registers. Data on the A or B bus egist will be clocked into the registers as the appropriate clock s 3-STATE outputs pin goes to a high logic level. Control G and direction pins s 300 mil slim DIP are provided to control the transceiver function. In the e transceiver mode, data present at the high impedance port r wit may be stored in either the A or the B register or in both.The select controls can multiplex stored and real-time h (transparent mode) data. The direction control determines which bus will receive data when the enable control G is 3- Active LOW. In the isolation mode (control G HIGH), A data ST may be stored in the B register and/or B data may be A stored in the A register.
