74HC7541D,118

The 74HC7541D,118 is an 8-bit buffer/line driver featuring Schmitt trigger inputs and 3-state outputs. It is part of the 74HC family from Nexperia and is designed for high noise immunity and low power dissipation. The device has two output enable inputs (OE1 and OE2); a HIGH on OEn causes the outputs to assume a high-impedance OFF-state. Inputs include clamp diodes, allowing current limiting resistors to interface inputs to voltages exceeding VCC. The Schmitt trigger inputs transform slowly changing input signals into sharply defined jitter-free output signals.

It operates over a wide supply voltage range of 2V to 6V, with an output current of 7.8mA typical per output (sink and source). The device is specified for an operating temperature range of -40°C to +125°C. It offers ESD protection: HBM exceeds 2000V and CDM exceeds 1000V, and latch-up performance exceeds 100mA per JESD 78 Class II Level B.

The 74HC7541D,118 is available in a 20-SOIC (0.295", 7.50mm Width) surface mount package, with the supplier device package 20-SO. It is RoHS3 compliant, MSL 1 Unlimited, and REACH unaffected (though compliance is low confidence). The device is suitable for applications requiring buffering of slow or noisy signals, such as in industrial control, automotive, and general-purpose logic interfacing.
