DM93L38

8-Bit Multiple Port Register

General Description

The DM93L38 is an 8-bit multiple port register designed for

high speed random access memory applications where the

ability to simultaneously read and write is desirable. A com-

mon use would be as a register bank in a three address

computer. Data can be written into any one of the eight bits

and read from any two of the eight bits simultaneously. The

circuit uses TTL technology and is compatible with all TTL

families.

Features

Master/slave operation permitting simultaneous write/

read without race problems

Simultaneously read two bits and write one bit in any

one of eight bit positions

Readily expandable to allow for larger word sizes
