74AHCT541A Octal buffer/line driver; 3-state Rev. 7 — 17 March 2017 1 Product data sheet 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 VCC range from 4.5 V to 5.5 V, the inputs are TTL 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 IOFF. The IOFF 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 tpd of 2.8 ns at 5 V Typical VOL(p) < 0.8 V at VCC = 5 V, Tamb = 25 °C Typical VOH(v) > 2.3 V at VCC = 5 V, Tamb = 25 °C Supports mixed-mode voltage operation on all ports IOFF circuitry provides partial Power-down mode operation 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.
