DESCRIPTION

The 74LCX07 is a low voltage CMOS OPEN DRAIN HEX BUFFER fabricated with sub-micron silicon gate and double-layer metal wiring C 2MOS technology. It is ideal for low power and high speed 3.3V applications. It can be interfaced to 5V signal environment for inputs. The internal circuit is composed of 2 stages including buffer output, which provides high noise immunity and stable output. It has same speed performance at 3.3V than 5V AC/ACT family, combined with a lower power consumption. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage. 74LCX07 LOW VOLTAGE CMOS HEX BUFFER (OPEN DRAIN) WITH 5V TOLERANT INPUTS Figure 1: Pin Connection And IEC Logic Symbols Table 1: Order Codes PACKAGE T & R SOP 74LCX07MTR TSSOP 74LCX07TTR TSSOPSOP Rev. 4

Table 8: AC Electrical Characteristics 1) Skew is defined as the absolute value of the difference between the actual propagation delay for any two outputs of the same device switch- ing in the same direction, either HIGH or LOW (tOSLH = | tPLHm - tPLHn |, tOSHL = | tPHLm - tPHLn |) 2) Parameter guaranteed by design Table 9: Capacitive Characteristics 1) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without load. (Refer to Test Circuit). Average operating current can be obtained by the following equation. ICC(opr) = CPD x VCC x fIN + ICC /6 (per gate) Figure 3: Test Circuit C L = 50 pF or equivalent (includes jig and probe capacitance) R L = R1 = 500Ω or equivalent R T = ZOUT of pulse generator (typically 50Ω ) Symbol Parameter Test Condition Value UnitVCC (V) C L (pF) R L (Ω ) ts = tr (ns) -40 to 85 °C -55 to 125 °C Min.
