FEATURES
16-bit parallel-to-serial conversion
16-bit serial-in, serial-out
Chip select control
Power supply current 48mA typical
Shift frequency 110MHz tyical
Available in 300mil-wide 24-pin Slim DIP package
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 (D0D15) 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 D0D15 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 V

C.
3. Not more than one output should be shorted at a time. For testing I
OS
, 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, I
OS
should be performed last.
