General Description
These devices incorporate an octal transceiver and an octal D-type register configured to enable transmission of data from bus to bus or internal register to bus. The DM74AS651 offers 64-Industrial grade product guaranteeing performance from −40°C to +85°C.
These bus transceivers feature totem-pole 3-STATE outputs designed specifically for driving highly-capacitive or relatively low-impedance loads. The high-impedance state and increased high-logic-level drive provide these devices with the capability of being connected directly to and driving 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, bidirectional bus drivers, and working registers
