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

output-enable (OE1, OE2) inputs can be used to

choose the modes of operation listed in the

function table.

Synchronous parallel loading is accomplished by

takingbothS0andS1high. Thisplacesthe3-state

outputs in a high-impedance state and permits

data that is 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 when the clear (CLR) input is low.

Taking either OE1 or OE2 high disables the outputs but has no effect on clearing, shifting, or storage of data.

The SN54F299 is characterized for operation over the full military temperature range of –55°C to 125°C. The

SN74F299 is characterized for operation from 0°C to 70°C.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
