They are specified in compliance with JEDEC standard no. 7. QUICK REFERENCE DATA GND = 0 V; Tamb = 25 C; tr = tf = 6 ns 74HC/HCT367 The 74HC/HCT367 are hex non-inverting buffer/line drivers with 3-state outputs. The 3-state outputs (nY) are controlled by the output enable inputs (1OE, 2OE). A HIGH on nOE causes the outputs to assume a high impedance OFF-state. The "367" is identical to the "368" but has non-inverting outputs. TYPICAL SYMBOL tPHL/ tPLH CI CPD Notes 1. CPD is used to determine the dynamic power dissipation (PD in W): PD = CPD x VCC2 x fi + (CL x VCC2 x fo) where: fi = input frequency in MHz fo = output frequency in MHz (CL x VCC2 x fo) = sum of outputs CL = output load capacitance in pF VCC = supply voltage in V 2. For HC the condition is VI = GND to VCC For HCT the condition is VI = GND to VCC - 1.5 V ORDERING INFORMATION See "74HC/HCT/HCU/HCMOS Logic Package Information".
