DM74LS375 Datasheet | National Semiconductor

Description The ’LS375 is a 4-bit D-type latch for use as temporary storage for binary information between processing units and input output or indicator units When its Enable (E) input is HIGH a latch is transparent i e the Q output will follow the D input each time it changes When E is LOW a latch stores the last valid data present on the D input preceding the HIGH-to-LOW transition of E The ’LS375 is functionally identical to the ’LS75 except for the corner power pins Connection Diagram Dual-In-Line Package Logic Symbol TL F 9830 - 2 TL F 9830 - 1 VCC e Pin 16 GND e Pin 8 Order Number DM74LS375M or DM74LS375N See NS Package Number M16A or N16E Pin Name D1- D4 E1 2 E3 4 Q1- Q4 Q1- Q4 Description Data Inputs Latches 1 2 Enable Inputs Latches 3 4 Enable Inputs Latch Outputs plementary Latch Outputs C1995 National Semiconductor Corporation TL F 9830 RRD-B30M115 Printed in U S A Absolute Maximum Ratings (Note) Supply Voltage Input Voltage Operating Free Air Temperature Range Storage Temperature Range 7V 7V 0 C to a 70 C b 65 C to a 150 C Note The ‘‘Absolute Maximum Ratings are those values beyond which the safety of the device cannot be guaranteed The device should not be operated at these limits The parametric values defined in the ‘‘Electrical Characteristics’’ table are not guaranteed at the absolute maximum ratings The ‘‘Remended Operating Conditions’’ table will define the conditions for actual device operation Remended Operating Conditions Symbol VCC VIH VIL IOH IOL TA ts (H) ts (L) th (H) th (L) tw (H) Parameter Supply Voltage High Level Input Voltage Low Level Input Voltage High Level Output Current Low Level Output Current Free Air Operating Temperature Setup Time HIGH or LOW Dn to En Hold Time HIGH or LOW Dn to En En Pulse Width HIGH 0 20 0 20 Min 4 75 2 08 b0 4 Nom 5 Max 5 25 Units V V V m A m A C ns ns ns 8 70 Electrical Characteristics Over remended operating free air temperature range (unless otherwise noted) Symbol VI VOH VOL Parameter Input...
