Each of the two 4-bit elements sources or sinks 7.8 mA per channel, which is typical for the 74HC family and sufficient to drive a few CMOS inputs or a low-power LED indicator without a separate buffer stage. ## Temperature grade and board-fit The 20-TSSOP package (supplier device package 20-TSSOP) has a 0.65 mm pin pitch and a body width of 4.40 mm, which fits standard fine-pitch SMD layouts. The same footprint is shared across many 74HC and 74HCT 20-pin TSSOP buffers, so a board designed for one can often accept the other with a BOM change only.","metaTitle":"SN74HC244PWR Texas Instruments 74HC Buffer, 2V-6V, 20-TSSOP","metaDescription":"SN74HC244PWR active-production 74HC octal buffer, 2V-6V supply, 3-state outputs, -40 to 85°C, 20-TSSOP.
