DESCRIPTION
The 74F676 contains 16 flip-flops with provision for synchronous parallel or serial entry and serial output. When the mode (M) input is High, information present on the parallel data (D0-D15) inputs is entered on the falling edge of the clock pulse (CP) input signal. When M is Low, data is shifted out of the most significant bit position while information present on the serial (SI) input shifts into the least significant bit position. A High signal on the chip select (CS) input prevents both parallel and serial operations. The 16 bit shift register operates in one of three modes, as indicated in the shift register Function Table. Hold: A High signal on the Chip Select (CS) input prevents clocking and data is stored in the 16 registers. Serial load: Data present on the SI pin shifts into the register on the falling edge of CP. Data enters the Q0 position and shifts toward Q15 on successive clocks finally appearing on the SO pin. Parallel load: Data present on D0-D15 is entered into the register on the falling edge of CP. The SO output represents the Q15 register output. To prevent false clocking, CP must be Low during a Low-to-High transition of CS.

NOTES: 1. For conditions shown as MIN or MAX, use the appropriate value under the recommended operating conditions for the applicable type. 2. All typical values are at VCC = 5V, Tamb = 25C. 3. Not more than one output should be shorted at a time. For testing IOS, the use of high-speed test apparatus and/or sample-and-hold techniques are preferable in order to minimize internal heating and more accurately reflect operational values. Otherwise, prolonged shorting of a High output may raise the chip temperature well above normal and thereby cause invalid readings in other parameter tests. In any sequence of parameter tests, IOS should be performed last.
