They are specified in compliance with JEDEC standard no. 7A. QUICK REFERENCE DATA GND = 0 V; Tamb = 25 °C; tr = tf = 6 ns 74HC/HCT7541 The 74HC/HCT7541 are octal Schmitt trigger non-inverting buffer/line drivers with 3-state outputs. The 3-state outputs are controlled by the output enable inputs OE1 and OE2. A HIGH on OEn causes the outputs to assume a high impedance OFF-state. The Schmitt trigger action in the data inputs transforms slowly changing input signals into sharply defined jitter-free output signals. The “7541” is identical to the “541” but has hysteresis on the data inputs. TYPICAL SYMBOL tPHL/ tPLH CI CPD Notes 1. CPD is used to determine the dynamic power dissipation (PD in W): PD = CPD × VCC2 × fi + ∑ (CL × ……
