Octal Bus Transceiver and Register
DM74AS651 • DM74AS652 Octal Bus Transceiver and Register October 1986 Revised July 2003 DM74AS651 DM74AS652 Octal Bus Transceiver and Register General Description Features These devices incorporate an octal transceiver and anSwitching specifications at 50 pF octal D-type register configured to enable transmission ofSwitching specifications guaranteed over full tempera- data from bus to bus or internal register to bus. The ture and V range CC DM74AS651 offers 64-Industrial grade product guarantee- Advanced oxide-isolated, ion-implanted Schottky TTL ing performance from −40°C to +85°C. process These bus transceivers feature totem-pole 3-STATE out- 3-STATE buffer-type outputs drive bus lines directly puts designed specifically for driving highly-capacitive or Guaranteed performance over industrial temperature relatively low-impedance loads. The high-impedance state range (−40°C to +85°C) in 64-grade products and increased high-logic-level drive provide these devices with the capability of being connected directly to and driv- ing the bus lines in a bus-organized system without need for interface or pull-up components. They are particularly attractive for implementing buffer registers, I/O ports, bidi- rectional bus drivers, and working registers. The registers in the DM74AS651 and DM74AS652 are edge-triggered D-type flip-flops. On the positive transition of the clock (CAB or CBA), the input data is stored. The SAB and SBA control pins are provided to select whether real-time data or stored data is transferred. A LOW input level selects real-time data and a HIGH level selects stored data. The select controls have a “make before break” configuration to eliminate a glitch which would nor- mally occur in a typical multiplexer during the transition between stored and real-time data. The Enable (GAB and GBA) control pins provide four modes of operation; real-time data transfer from bus A-to- B, real-time data transfer from bus B-to-A, real-time bus A and/or B data transfer to internal storage, or internal stored data transfer to bus A and/or B.
