It stores one of eight data bits selected by a three-bit address, with the remaining outputs held in a known high-impedance state. The 13 ns typical propagation delay keeps the latch responsive in clocked systems up to roughly 38 MHz — fast enough for most control and register-bank applications in industrial logic. This makes the latch suitable for outdoor telecom cabinets, engine-bay control modules, and downhole instrumentation where the ambient temperature swings beyond the commercial 0°C to 70°C range. The 74HC family's CMOS logic levels are consistent across this span — no derating of the input threshold or output drive at the extremes beyond the datasheet's temperature curves. The standard output type means the latch drives rail-to-rail CMOS levels, not open-drain or three-state on the output side. For bus-oriented designs where multiple outputs share a line, a separate three-state buffer is needed — the latch itself does not tri-state its outputs.","metaTitle":"CD74HC259MT Texas Instruments 74HC Addressable Latch","metaDescription":"CD74HC259MT from Texas Instruments — 74HC D-Type Addressable Latch, 1:8 circuit, 2V-6V supply, 13ns propagation delay, -55°C to 125°C, 16-SOIC.
