74AHC9541A Octal buffer/line driver 3-state Rev. 1 28 June 2017 Product data sheet 1 General description The 74AHC9541A is an 8-bit buffer/line driver with 3-state outputs and Schmitt trigger inputs. The device features an output enable input (OE) and select input (S). A HIGH on OE causes the associated outputs to assume a high-impedance OFF-state. A LOW on the select input S causes the buffer/line driver to act as an inverter. Inputs are overvoltage tolerant. This feature allows the use of these devices as translators in mixed voltage environments. The data (An), select (S) and output enable (OE) inputs include Schmitt trigger inputs, capable of transforming slowly changing input signals into sharply defined, jitter-free output signals. 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 Wide supply voltage range from 1.8 V to 5.5 V Typical t of 5.1 ns at 5 V pd Typical V < 0.8 V at V = 3.3 V, T = 25 C OL(p) CC amb Typical V > 2.3 V at V = 3.3 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.
