SN54ALS299, SN74ALS299 8-BIT UNIVERSAL SHIFT/STORAGE REGISTERS WITH 3-STATE OUTPUTS SDAS220B – DECEMBER 1982 – REVISED DECEMBER 1994 • • • • • description These 8-bit universal shift /storage registers feature multiplexed I/O ports to achieve full 8-bit data handling in a single 20-pin package. Two function-select (S0, S1) inputs and two outputenable (OE1, OE2) inputs can be used to choose the modes of operation listed in the function table.

This places the 3-state outputs in the high-impedance state and permits data applied on the I/O ports to be clocked into the register. Reading out of the register can be accomplished while the outputs are enabled in any mode. Clearing occurs asynchronously when the clear (CLR) input is low. Taking either OE1 or OE2 high disables the outputs, but has no effect on clearing, shifting, or storing data. The SN54ALS299 is characterized for operation over the full military temperature range of – 55°C to 125°C. The SN74ALS299 is characterized for operation from 0°C to 70°C.
