SN74LS194AD集成电路（IC）的移位寄存器规格书PDF中文资料

   

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
