74LV126 Datasheet | Philips Semiconductors

FEATURES - Wide operating voltage: 1.0 to 5.5 V - Optimized for low voltage applications: 1.0 to 3.6 V - Accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V - Typical VOLP (output ground bounce) < 0.8 V at VCC = 3.3 V, Tamb = 25°C DESCRIPTION The 74LV126 is a low-voltage Si-gate CMOS device that is pin and function patible with 74HC/HCT126. The 74LV126 consists of four non-inverting buffers/line drivers with 3-state outputs. The 3-state outputs (n Y) are controlled by the output enable input (n OE). A LOW at n OE causes the outputs to assume a high impedance OFF-state. - - - Typical VOHV (output VOH undershoot) > 2 V at VCC = 3.3 V, Tamb = 25°C Output capability: bus driver ICC category: MSI QUICK REFERENCE DATA GND = 0 V; Tamb = 25°C; tr = tf ≤ 2.5 ns SYMBOL t PHL/t PLH CI CPD PARAMETER Propagation delay n A to n Y Input capacitance Power dissipation capacitance per buffer VCC = 3.3 V; VI = GND to VCC1 CONDITIONS CL = 15 p F; VCC = 3.3 V TYPICAL 9 3.5 23 UNIT ns p F p F NOTE: 1. CPD is used to determine the dynamic power dissipation (PD in µW) PD = CPD × VCC2 × fi )ȍ (CL × VCC2 × fo) where: fi = input frequency in MHz; CL = output load capacitance in p F; fo = output frequency in MHz; VCC = supply voltage in V; ȍ (CL × VCC2 × fo) = sum of the outputs.
