Texas Instruments 8-Bit Non-Inverting TTL Bus Transceiver, 20-Pin PDIP SN74LS245N

The Texas Instruments SN74LS245N is an 8-Bit Non-Inverting TTL Bus Transceiver designed for efficient data transfer in digital systems. Packaged in a 20-pin PDIP for through-hole mounting, this IC supports bidirectional data communication across eight independent channels, facilitating smooth and fast signal routing between buses.

Operating within a supply voltage range of 4.75V to 5.25V and functioning reliably across temperatures from 0°C to 70°C, the SN74LS245N is suitable for a variety of industrial and commercial electronics applications requiring logic ICs.

Its advanced bipolar junction transistor technology combined with Schottky diode clamps in the 74LS family provides lower power consumption while matching speeds of the original 74TTL logic ICs. The device delivers 3-state outputs with maximum propagation delay of only 12ns, making it ideal for timing-sensitive systems such as communication, computing, and embedded control.

With a maximum high-level output current of -15mA and maximum low-level output current of 24mA, the IC supports strong signal drive capability. The non-inverting polarity and logic level TTL input/output ensure compatibility and signal integrity within digital electronics circuits.

The SN74LS245N’s compact dimensions of 24.33mm length and 4.57mm height facilitate easy integration onto standard PCB designs. Its through-hole package type offers mechanical stability and ease of assembly.

This bus transceiver is widely used in laboratory instruments, industrial automation, embedded systems, and electronic component assemblies where reliable data multiplexing and bus interfacing are critical.

Features 8 independent channels for bidirectional bus communication. Operates within a supply voltage range of 4.75V to 5.25V. Ensures high-speed operation with a maximum propagation delay of 12 nanoseconds. Designed for robust TTL input and output levels with 3-state outputs.

Temperature range supported from 0°C to 70°C for reliable performance. Compact dimensions with length 24.33mm and height 4.57mm. Maximum high-level output current of -15mA and maximum low-level current of 24mA. Through-hole mount type with 20 pins in standard PDIP packaging.
