74AHCT541A Octal buffer/line driver 3-state Rev. 7 17 March 2017 Product data sheet 1 General description The 74AHCT541A is an 8-bit buffer/line driver with 3-state outputs and TTL inputs. The device features two output enables (OE1 and OE2). A HIGH on OEn causes the associated outputs to assume a high-impedance OFF-state. Designed to operate over a V range from 4.5 V to 5.5 V, the inputs are TTL CC compatible, which allows the device to be used to translate from 3.3 V to 5 V. Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times. 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 2.8 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 3kV MM JESD22-A115-A exceeds 200 V CDM JESD22-C101E exceeds 2kV Specified from -40 C to +85 C and from -40 C to +125 C 3 Ordering information Table 1.
