Octal 3-STATE Bus Driver
DM74ALS244A Octal 3-STATE Bus Driver September 1986 Revised February 2000 DM74ALS244A Octal 3-STATE Bus Driver General Description Features This octal 3-STATE bus driver is designed to provide the �Advanced low power oxide-isolated ion-implanted designer with flexibility in implementing a bus interface with Schottky TTL process memory, microprocessor, or communication systems. This � Functional and pin compatible with the 74LS counterpart device offers 64-extended temperature Grade product � Improved switching performance with less power dissi- guaranteeing performance from −40°C to +85°C. The out- pation compared with the 74LS counterpart put 3-STATE gating control is organized into two separate � Switching response specified into 500Ω and 50 pF load groups of four buffers, and both control inputs enable the respective outputs when set logic LOW. The 3-STATE cir- � Switching response specifications guaranteed over full temperature and V supply range cuitry contains a feature that maintains the buffer outputs in CC 3-STATE (high impedance state) during power supply � PNP input design reduces input loading ramp-up or ramp-down. This eliminates bus glitching prob- lems that arise during power-up and power-down.
