MICROCIRCUIT DATA SHEET Original Creation Date: 04/15/98 Last Update Date: 07/08/98 Last Major Revision Date: 04/15/98 MNDM54LS373-X REV 0A0 OCTAL TRANSPARENT LATCH with TRI-STATE OUTPUTS General Description The 'LS373 consists of eight latches applications. The flip-flops appear HIGH. When LE is LOW, the data that the bus when the Output Enable (/OE) high impedance state. with Tri-state outputs for bus organized system transparent to the data when Latch Enable (LE) is meets the setup times is latched. Data appears on is LOW. When /OE is HIGH the bus output is in the Industry Part Number NS Part Numbers 54LS373 DM54LS373J/883 Prime Die R373 Processing Subgrp Description MIL-STD-883, Method 5004 1 2 3 4 5 6 7 8A 8B 9 10 11 Quality Conformance Inspection MIL-STD-883, Method 5005 1 Static tests at Static tests at Static tests at Dynamic tests at Dynamic tests at Dynamic tests at Functional tests at Functional tests at Functional tests at Switching tests at Switching tests at Switching tests at Temp ( oC) +25 +125 -55 +25 +125 -55 +25 +125 -55 +25 +125 -55 MICROCIRCUIT DATA SHEET MNDM54LS373-X REV 0A0 Features 2 MICROCIRCUIT DATA SHEET MNDM54LS373-X REV 0A0 (Absolute Maximum Ratings) (Note 1) Storage Temperature -65 C to +150 C Ambient Temperature under Bias -55 C to +125 C Input Voltage -0.5V to +7.0V VCC Pin Potential to Ground Pin -0.5V to +7.0V Junction Temperature under Bias -55C to +175C Current Applied to Output in LOW state (Max) twice the rated Iol (ma) Note 1: Absolute Maximum ratings are those values beyond which the device may be damaged or have its useful life impaired.
