Part # 74LS173 datasheet

Part Manufacturer: Motorola


Part Description: 74LS173

Part Details:

SN54/74LS173A 4-BIT D-TYPE REGISTERWITH 3-STATE OUTPUTS The SN54 / 74LS173A is a high-speed 4-Bit Register featuring 3-state outputs for use in bus-organized systems. The clock is fully edge-triggeredallowing either a load from the D inputs or a hold (retain register contents) 4-BIT D-TYPE REGISTER depending on the state of the Input Enable Lines (IE1, IE2). A HIGH on either WITH 3-STATE OUTPUTS Output Enable line (OE1, OE2) brings the output to a high impedance state LOW POWER SCHOTTKY without affecting the actual register contents. A HIGH on the Master Reset(MR) input resets the Register regardless of the state of the Clock (CP), theOutput Enable (OE1, OE2) or the Input Enable (IE1, IE2) lines.· Fully Edge-Triggered · 3-State Outputs · Gated Input and Output Enables J SUFFIX · Input Clamp Diodes Limit High-Speed Termination Effects CERAMIC CASE 620-09 16 1 CONNECTION DIAGRAM DIP (TOP VIEW) N SUFFIX VCC MR D0 D1 D2 D IE 3 2 IE1 PLASTIC 16 15 14 13 12 11 10 9 CASE 648-08 16 1 NOTE:The Flatpak versionhas the same pinouts(Connection Diagram) as D SUFFIX the Dual In-Line Package.
