74HC7541 74HCT7541 Octal Schmitt trigger buffer/line driver 3-state Rev. 8 3 August 2021 Product data sheet 1. General description The 74HC7541 74HCT7541 is an 8-bit buffer/line driver with Schmitt-trigger inputs and 3-state outputs. The device features two output enables (OE1 and OE2). A HIGH on OEn causes the outputs to assume a high-impedance OFF-state. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of V . Schmitt trigger inputs CC transform slowly changing input signals into sharply defined jitter-free output signals. 2. Features and benefits Wide supply voltage range from 2.0 to 6.0 V CMOS low power dissipation High noise immunity Unlimited input rise and fall times Latch-up performance exceeds 100 mA per JESD 78 Class II Level B Complies with JEDEC standards: JESD8C (2.7 V to 3.6 V) JESD7A (2.0 V to 6.0 V) Non-inverting outputs Input levels: For 74HC7541: CMOS level For 74HCT7541: TTL level ESD protection: HBM JESD22-A114F exceeds 2000 V MM JESD22-A115-A exceeds 200 V Specified from -40 C to +85 C and from -40 C to +125 C 3.
