54LS75, 54LS77, 4-BIT D LATCH
4-BIT D LATCH The TTL/MSI SN54 / 74LS75 and SN54 / 74LS77 are latches used as temporary storage for binary information between processing units and input /output or indicator units.
Information present at a data (D) input is transferred to the Q output when the Enable is HIGH and the Q output will follow the data input as long as the Enable remains HIGH.
When the Enable goes LOW, the information (that was present at the data input at the time the transition occurred) is retained at the Q output
54LS75 Features
* complementary Q and Q output from a 4-bit latch and is available in the 16-pin packages. For higher component density applications the SN54 / 74LS77 4-bit latch is available in the 14-pin package with Q outputs omitted. CONNECTION DIAGRAMS DIP (TOP VIEW) Q0 Q1 Q1 E0
