Each buffer drives up to 6 mA source or sink at 5V supply, enough for a few CMOS or TTL loads on a backplane or control bus. The 3-state enable per element lets you gate each channel individually — useful for shared data lines where one buffer at a time drives the bus. ## Temperature range and deployment Rated from -55°C to 125°C, the CD74HCT126E covers military and industrial extremes. It fits in avionics black boxes, satellite telemetry interfaces, downhole instrumentation, and outdoor telecom gear where the ambient can swing hard. The through-hole 14-DIP package (0.300\" body) is a standard footprint for prototyping, breadboard verification, and legacy board repair — no fine-pitch soldering required.","metaTitle":"CD74HCT126E 74HCT Quad Buffer, Non-Inverting, 3-State","metaDescription":"CD74HCT126E quad non-inverting buffer with 3-state outputs in 14-DIP. 4.5V-5.5V supply, -55°C to 125°C range, 6mA drive.
