SN54ALS573C, SN54AS573A, SN74ALS573C, SN74AS573A OCTAL D-TYPE TRANSPARENT LATCHES WITH 3-STATE OUTPUTS SDAS048D – DECEMBER 1989 – REVISED JANUARY 1995 OE 1D 2D 3D 4D 5D 6D 7D 8D GND description These octal D-type transparent latches feature 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. They are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers. 1 20 2 19 3 18 4 17 5 16 6 15 7 14 8 13 9 12 10 11 VCC 1Q 2Q 3Q 4Q 5Q 6Q 7Q 8Q LE 2D 1D SN54ALS573C, SN54AS573A . . . FK PACKAGE (TOP VIEW) While the latch-enable (LE) input is high, outputs (Q) respond to the data (D) inputs. When LE is low, the outputs are latched to retain the data that was set up. 3D 4D 5D 6D 7D 4 2 1 20 19 18 5 17 6 16 7 15 8 14 9 10 11 12 13 2Q 3Q 4Q 5Q 6Q 8D GND LE 8Q 7Q A buffered output-enable (OE) input can be used to place the eight outputs in either a normal logic state (high or low) or a high-impedance state. In the high-impedance state, the outputs neither load nor drive the bus lines significantly. The high-impedance state and the increased drive provide the capability to drive bus lines without interface or pullup components. 3 1Q • • • SN54ALS573C, SN54AS573A . . .

Old data can be retained or new data can be entered while the outputs are in the high-impedance state. The SN54ALS573C and SN54AS573A are characterized for operation over the full military temperature range of – 55°C to 125°C. The SN74ALS573C and SN74AS573A are characterized for operation from 0°C to 70°C.

None: Not yet available Lead (Pb-Free). Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Green (RoHS & no Sb/Br): TI defines "Green" to mean "Pb-Free" and in addition, uses package materials that do not contain halogens, including bromine (Br) or antimony (Sb) above 0.1% of total product weight.
