DM74ALS373 Octal D-Type TRI-STATE Transparent Latch March 1996 DM74ALS373 Octal D-Type TRI-STATE Transparent Latch General Description These 8-bit registers feature totem-pole TRI-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 registers 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 The eight latches of the ALS373 are transparent D-type latches While the enable (G) is high the Q outputs will follow the data (D) inputs When the enable is taken low the output will be latched at the level of the data that was set up A buffered output control input can be used to place the eight outputs in either a normal logic state (high or low logic levels) or a high-impedance state In the high-impedance state the outputs neither load nor drive the bus lines significantly The output control does not affect the internal operation of the latches That is the old data can be retained or new data can be entered even while the outputs are off Features Y Y Y Y Y Y Switching specifications at 50 pF Switching specifications guaranteed over full temperature and VCC range Advanced oxide-isolated ion-implanted Schottky TTL process Functionally a……
