What are the key features of SN74LS378D?
- Hex (6-bit) D-type flip-flop with active-high clock enable and hold mode for selective data capture
- Maximum clock frequency of 30MHz with 15pF load capacitance in LS TTL technology
- 8mA maximum output sink current (IOL) suitable for driving standard TTL and CMOS logic loads
- 16-pin SOIC surface-mount package with RoHS e4 lead-free compliant construction
What is SN74LS378D used for?
The SN74LS378D is used in digital logic systems requiring 6-bit parallel data storage with selective clock enable, such as microprocessor output latches, bus interface registers, and address storage in embedded control boards. Its hold mode allows the stored data to remain unchanged when the clock enable is deasserted, making it ideal for pipeline stages and synchronization circuits in FPGA peripheral glue logic. Engineers also deploy it in display drivers, LED controllers, and parallel I/O port expansion circuits where multiple independent bits must be latched simultaneously.

Frequently Asked Questions
What is the SN74LS378D and what makes it different from a standard flip-flop?
The SN74LS378D is a hex D-type flip-flop with a clock enable input that allows selective clocking of all 6 flip-flops simultaneously. Unlike a basic D flip-flop, it includes a hold mode where data is retained when the enable is low, making it suitable for selective data capture in bus systems and register files.
What is the maximum operating frequency of the SN74LS378D?
The SN74LS378D is rated for a maximum clock frequency of 30MHz at nominal supply voltage with a 15pF load capacitance, which is sufficient for standard TTL-speed digital logic in embedded control, data path, and bus interface applications operating at conventional clock rates.
What package does the SN74LS378D come in?
The SN74LS378D is available in a 16-pin SOIC (Small Outline Integrated Circuit) surface-mount package, as indicated by the JESD-30 code R-PDSO-G16. This package offers a compact SMD footprint while maintaining compatibility with standard 16-pin through-hole footprint spacing for easy PCB layout migration.
Is the SN74LS378D RoHS compliant?
Yes, the SN74LS378D carries the JESD-609 e4 code indicating it is available in a lead-free, RoHS-compliant version. This makes it suitable for use in modern electronics manufacturing environments that require environmentally responsible component materials and assembly processes.
What are typical applications for the SN74LS378D?
The SN74LS378D is commonly used in microprocessor output port latches, memory address registers, data bus interfaces, and pipeline registers in digital control systems. Its 6-bit width and clock enable are ideal for applications requiring byte-wide minus two bits, such as 6-bit DAC interfaces, display segment drivers, and relay output control circuits.
