SN74LS194A

SN74LS194A 4−Bit Bidirectional Universal Shift Register The SN74LS194A is a High Speed 4-Bit Bidirectional Universal Shift Register. As a high speed multifunctional sequential building block, it is useful in a wide variety of applications. It may be used in serial-serial, shift left, shift right, serial-parallel, parallel-serial, and parallel-parallel data register transfers. The LS194A is similar in operation to the LS195A Universal Shift Register, with added features of shift left without external connections and hold (do nothing) modes of operation. It utilizes the Schottky diode clamped process to achieve high speeds and is fully compatible with all ON Semiconductor TTL families. Typical Shift Frequency of 36 MHz Asynchronous Master Reset Hold (Do Nothing) Mode Fully Synchronous Serial or Parallel Data Transfers Input Clamp Diodes Limit High Speed Termination Effects GUARANTEED OPERATING RANGES Symbol Parameter Min Typ Max Unit VCC Supply Voltage TA Operating Ambient Temperature Range 4.75 5.0 5.25 V 0 25 70 °C IOH Output Current − High IOL Output Current − Low −0.4 mA 8.0 mA http://onsemi.com LOW POWER SCHOTTKY 16 1 PLASTIC N SUFFIX CASE 648 16 1 SOIC D SUFFIX CASE 751B ORDERING INFORMATION Device Package Shipping SN74LS194AN 16 Pin DIP 2000 Units/Box SN74LS194AD SOIC−16 38 Units/Rail SN74LS194ADR2 SOIC−16 2500/Tape & Reel © Semiconductor Components Industries, LLC, 2006 1 July, 2006 − Rev. 8 Publication Order Number: SN74LS1...
