|SN74ALS373A, SN74AS373 OCTAL TRANSPARENT D-TYPE LATCHES WITH 3-STATE OUTPUTS
Eight Latches in a Single Package 3-State Bus-Driving True Outputs Full Parallel Access for Loading Buffered Control Inputs pnp Inputs Reduce dc Loading on Data Lines Package Options Include Plastic Small-Outline (DW) Packages, Ceramic Chip Carriers (FK), and Standard Plastic (N) and Ceramic (J) 300-mil DIPs These octal transparent D-type 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. While the latch-enable (LE) input is high, the Q outputs follow the data (D) inputs. When LE is taken low, the Q outputs are latched at the logic levels set up at the D inputs. 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.
OE does not affect internal operations of the latches. Old data can be retained or new data can be entered while the outputs are off. The SN54ALS373 and SN54AS373 are characterized for operation over the full military temperature range to 125°C. The SN74ALS373A and SN74AS373 are characterized for operation from to 70°C.FUNCTION TABLE (each latch) INPUTS OE LE OUTPUT Q0 Z

electrical characteristics over recommended operating free-air temperature range (unless otherwise noted)
Outputs disabled All typical values are at VCC = 25°C. The output conditions have been chosen to produce a current that closely approximates one half of the true short-circuit output current, IOS.
