The SN74LS367AD from Texas Instruments is a dual non-inverting buffer from the 74LS TTL family. It features two channels with 3-State outputs, capable of sinking 24mA and sourcing 2.6mA. Designed for 5V systems, it operates within a 4.75V to 5.25V supply range. Housed in a 16-SOIC package, it is ideal for bus driving, memory address buffering, and other high-capacitance load applications in legacy and current TTL-based digital systems.
- 3-State Outputs: Enable bus sharing and isolation, critical for multiplexed data and address lines.
- High Sink Current (24mA): Provides robust drive capability for TTL loads and high-capacitance bus lines.
- Proven 74LS Technology: Ensures compatibility with existing TTL logic families and legacy designs.
- Non-Inverting Configuration: Simplifies design by preserving the original signal logic state.
Bus Line Driving in 5V Systems
Use the SN74LS367AD to drive data and address buses in 5V TTL systems. The 3-State outputs allow multiple devices to share the same bus without contention, as outputs can be put into a high-impedance state.
Memory Address Buffering
Buffer address lines from a CPU or memory controller to multiple memory chips. The high sink current (24mA) ensures fast and reliable charging and discharging of the address line capacitance.
Peripheral Interface Buffering
Interface between a microprocessor and peripheral devices like UARTs, timers, or I/O ports. The non-inverting buffer preserves signal polarity while providing the necessary drive strength.
Multiplexed Data Bus Isolation
In systems with multiplexed data buses, the 3-State outputs can isolate different sections of the bus when not in use, preventing signal interference and reducing power consumption.
Legacy TTL System Design
For maintaining or designing new systems that must interface with legacy TTL components, this buffer ensures proper voltage and current levels for reliable operation.
Test Equipment and Instrumentation
In bench test equipment, this buffer can be used to drive long cables or high-capacitance loads, ensuring signal integrity over extended distances.
