HD74HC673
16-bit Shift Register
Description
The HD74HC673 is a 16-bit shift register and a 16-bit storage register in a single 24-pin package. A three-
state input/output (data I/O) port to the shift register allows serial entry and/or reading of data. The storage
register is connected in a parallel data loop with the shift register and may be asynchronously cleared by
taking the store-clear input low. The storage register may be parallel loaded with shift-register data to
provide shift-register status via the parallel outputs. The shift register can be parallel loaded with the
storage-register data upon command.
A high logic level at the chip-select (CS) input disables both the shift-register clock and the storage register
clock and places the data I/O in the high-impedance state. The store-clear function is not disabled by the
chip select.
Caution must be exercised to prevent false clocking of either the shift register or the storage register via the
chip-select input. The shift clock should be low during the low-to-high transition of chip select and the
store clock should be low during the high-to-low transition of chip select.
Features
High Speed Operation: tpd (MODE/STRCLK to Y) = 23 ns typ (CL = 50 pF)
High Output Current: Fanout of 15 LSTTL Loads (Q15 output)
Wide Operating Voltage: VCC = 2 to 6 V
Low Input Current: 1 µA max
Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C)
