description

The ’173 and ’LS173A 4-bit registers include

D-type flip-flops featuring totem-pole 3-state

outputs capable of driving highly capacitive

or relatively low-impedance loads. The

high-impedance third state and increased

high-logic-level drive provide these flip-flops with

the capability of being connected directly to and

NC – No internal connection

driving the bus lines in a bus-organized system without need for interface or pull-up components. Up to 128 of

the SN74173 or SN74LS173A outputs can be connected to a common bus and still drive two Series 54/74 or

54LS/74LS TTL normalized loads, respectively. Similarly, up to 49 of the SN54173 or SN54LS173A outputs can

be connected to a common bus and drive one additional Series 54/74 or 54LS/74LS TTL normalized load,

respectively. To minimize the possibility that two outputs will attempt to take a common bus to opposite logic

levels, the output control circuitry is designed so that the average output disable times are shorter than the

average output enable times.

Gated enable inputs are provided on these devices for controlling the entry of data into the flip-flops. When both

data-enable (G1, G2) inputs are low, data at the D inputs are loaded into their respective flip-flops on the next

positive transition of the buffered clock input. Gate output-control (M, N) inputs also are provided. When both

are low, the normal logic states (high or low levels) of the four outputs are available for driving the loads or bus

lines. The outputs are disabled independently from the level of the clock by a high logic level at either

output-control input. The outputs then present a high impedance and neither load nor drive the bus line. Detailed

operation is given in the function table.

The SN54173 and SN54LS173A are characterized for operation over the full military temperature range of

–55°C to 125°C. The SN74173 and SN74LS173A are characterized for operation from 0°C to 70°C.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

On products compliant to MIL-PRF-38535, all parameters are tested

unless otherwise noted. On all other products, production

processing does not necessarily include testing of all parameters.

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.
