| LESHAN RADIO COMPANY, LTD. Noninverting 3-State Buffer L74VHC1G125 The L74VHC1G125 is an advanced high speed CMOS noninverting 3 state buffer fabricated with silicon gate noninverting 3 state buffer fabricated with silicon gate CMOS technology. It achieves high speed operation similar to equivalent Bipolar Schottky TTL while maintaining CMOS low power dissipation. The internal circuit is composed of three stages, including a buffered 3-state output which provides high noise immunity and stable output. The L74VHC1G125 input structure provides protection when voltages up to 7.0V are applied,regardless of the supply voltage. This allows the L74VHC1G125 to be used to interface 5.0V circuits to 3.0V circuits. Features * * * * * * * High Speed: tPD = 3.5 ns (Typ) at VCC = 5.0 V Low Power Dissipation: ICC = 1 mA (Max) at TA = 25C Power Down Protection Provided on Inputs Balanced Propagation Delays Pin and Function Compatible with Other Standard Logic Families Chip Complexity: FETs = 58; Equivalent Gates = 15 Pb-Free Packages are Available 5 4 MARKING DIAGRAMS 5 1 2 3 SC-88A/SOT-353/SC-70 DF SUFFIX W0 M G G OE 1 5 VCC 1 GND 5 4 M 5 IN A 2 3 4 OUT Y Figure 1.

CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating current consumption without load. Average operating current can be obtained by the equation: ICC(OPR) = CPD VCC fin + ICC. CPD is used to determine the no-load dynamic power consumption; PD = CPD VCC2 fin + ICC VCC. 3/6 LESHAN RADIO COMPANY, LTD.
