It handles 7.8 mA source and sink per output, typical for driving bus lines or LED indicators in mixed-voltage 5V/3.3V systems. ## Through-hole DIP integration and supply rails Housed in a 20-pin DIP (0.300\" body width, 7.62 mm row spacing), the CD74HC244E is a through-hole part that mates with standard DIP sockets or wave-solder holes on a 0.100\" pitch grid. Supply voltage tolerance from 2V to 6V means the same BOM line works on a 3.3V microcontroller bus and a 5V legacy backplane — no separate regulator needed per voltage domain.","metaTitle":"CD74HC244E Texas Instruments 74HC Buffer, 3-State, 20-DIP","metaDescription":"CD74HC244E TI 74HC buffer non-inverting with 3-state output, 2V-6V supply, -55°C to 125°C, 20-DIP.

Both are 20-pin DIP packages, but the pin functions differ — the CD74HC244E has two 4-bit sections with separate output-enable pins, whereas the SN74LS645-1N has direction and enable controls for a single 8-bit bus. A board wired for the transceiver needs a layout change to accept the buffer."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/CD74HC244E","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/CD74HC244E when reusing this data.
