74AHCT17A Hex buffer Schmitt trigger Rev. 1 18 May 2017 Product data sheet 1 General description The 74AHCT17A is a hex buffer with Schmitt-trigger inputs, capable of transforming slowly changing input signals into sharply defined, jitter-free output signals. Designed to operate over a V range from 4.5 V to 5.5 V, the inputs are TTL CC compatible. This range allows the device to be used to translate from 3.3 V to 5 V. This device is fully specified for partial Power-down applications using I . The I OFF OFF circuitry disables the output, preventing the damaging backflow current through the device when it is powered down. 2 Features and benefits Direct interface with TTL levels Supply voltage range from 4.5 V to 5.5 V Typical t of 3.2 ns at 5 V pd Typical V < 0.8 V at V = 5 V, T = 25 C OL(p) CC amb Typical V > 2.3 V at V = 5 V, T = 25 C OH(v) CC amb Supports mixed-mode voltage operation on all ports I circuitry provides partial Power-down mode operation OFF Latch-up performance exceeds 250 mA per JESD 78 Class II ESD protection: HBM ANSI/ESDA/JEDEC JS-001 Class 2 exceeds 3 kV MM JESD22-A115-A exceeds 150 V CDM JESD22-C101E exceeds 2 kV Specified from -40 C to +85 C and from -40 C to +125 C 3 Ordering information Table 1.
