SN74HC240APWRG4 Octal Buffer/Line Driver from Texas Instruments

The SN74HC240APWRG4 is a high-quality octal buffer and line driver designed to provide bidirectional drive currents for bus-oriented systems. Manufactured by Texas Instruments, a leader in the semiconductor industry, this integrated circuit is part of the 'HC' logic family, which is well-known for its high-speed CMOS technology.

This versatile device features eight independent buffers with 3-state outputs, which can be used as either line drivers or receivers. Each buffer has two operational modes: non-inverting with active-high enable inputs and inverting with active-low enable inputs. This flexibility allows for the easy interfacing with different logic levels and provides a convenient way to control the flow of data in digital systems.

The SN74HC240APWRG4 operates over a wide voltage range from 2V to 6V, making it compatible with various logic families and ensuring reliable operation in a broad spectrum of applications. Its robust design allows it to drive up to 15 LSTTL loads, which is significant for interfacing with legacy systems and ensuring compatibility with a wide range of digital components.

The device comes in a TSSOP (Thin Shrink Small Outline Package) form factor under the part number SN74HC240APWRG4, which provides a compact footprint while still offering excellent thermal performance. This package is ideal for space-constrained applications where board real estate is at a premium.

Key features of the SN74HC240APWRG4 include:
