74LS374 Product details

Description

These 8-bit registers feature totem-pole TRI-STATE outputs designed specifically for driving highly-capacitive or relative- ly low-impedance loads The high-impedance state and in- creased high-logic level drive provide these registers with the capability of being connected directly to and driving the bus lines in a bus-organized system without need for inter- face or pull-up components They are particularly attractive for implementing buffer registers I O ports bidirectional bus drivers

Features

Y Choice of 8 latches or 8 D-type flip-flops in a single package Y TRI-STATE bus-driving outputs Y Full parallel-access for loading Y Buffered control inputs Y P-N-P inputs reduce D-C loading on data lines Connection Diagrams Dual-In-Line Packages ’LS373 Order Number DM54LS373J DM54LS373W DM74LS373N or DM74LS373WM See NS Package Number J20A M20B N20A or W20A ’LS374 TL F 6431.
