TL/F/5297 M M 5 4 H C 0 8 / M M 7 4 H C 0 8 Q u a d 2 -In p u t A N D G a te January 1988 MM54HC08/MM74HC08 Quad 2-Input AND Gate General Description These AND gates utilize advanced silicon-gate CMOS tech- nology to achieve operating speeds similar to LS-TTL gates with the low power consumption of standard CMOS inte- grated circuits. The HC08 has buffered outputs, providing high noise immunity and the ability to drive 10 LS-TTL loads. The 54HC/74HC logic family is functionally as well as pin- out compatible with the standard 54LS/74LS logic family. All inputs are protected from damage due to static dis- charge by internal diode clamps to VCC and ground. Features Y Typical propagation delay: 7 ns (tPHL), 12 ns (tPLH) Y Fanout of 10 LS-TTL loads Y Quiescent power consumption: 2 mA maximum at room temperature Y Low input current: 1 mA maximum Connection Diagram Dual-In-Line Package TL/F/5297–1 Top View Order Number MM54HC08 or MM74HC08 C1995 National Semiconductor Corporation RRD-B30M105/Printed in U.

Note 4: For a power supply of 5V g10% the worst case output voltages (VOH, and VOL) occur for HC at 4.5V. Thus the 4.5V values should be used when designing with this supply. Worst case VIH and VIL occur at VCCe5.5V and 4.5V respectively. (The VIH value at 5.5V is 3.85V.) The worst case leakage current (IIN, ICC, and IOZ) occur for CMOS at the higher voltage and so the 6.0V values should be used. **VIL limits are currently tested at 20% of VCC. The above VIL specification (30% of VCC) will be implemented no later than Q1, CY’89. 2 AC Electrical Characteristics VCCe5V, TAe25§C, CLe15 pF, tretfe6 ns Symbol Parameter Conditions Typ Guaranteed Units Limit tPHL Maximum Propagation 12 20 ns Delay, Output High to Low tPLH Maximum Propagation 7 15 ns Delay, Output Low to High AC Electrical Characteristics VCCe2.0V to 6.0V, CLe50 pF, tretfe6 ns (unless otherwise specified) TAe25§C 74HC 54HC Symbol Parameter Conditions VCC TAeb40 to 85§C TAeb55 to 125§C Units Typ Guaranteed Limits tPHL Maximum Propagation 2.0V 77 121 151 175 ns Delay, Output High to Low 4.5V 15 24 30 35 ns 6.0V 13 20 25 30 ns tPLH Maximum Propagation 2.0V 30 90 113 134 ns Delay, Output 4.5V 10 18 23 27 ns Low to High 6.0V 8 15 19 23 ns tTLH, tTHL Maximum Output Rise 2.0V 30 75 95 110 ns and Fall Time 4.5V 8 15 19 22 ns 6.0V 7 13 16 19 ns CPD Power Dissipation (per gate) 38 pF Capacitance (Note 5) CIN Maximum Input 4 10 10 10 pF Capacitance Note 5: CPD determines the no load dynamic power consumption, PDeCPD VCC2 faICC VCC, and the no load dynamic current consumption, ISeCPD VCC faICC. 3 M M 5 4 H C 0 8 / M M 7 4 H C 0 8 Q u a d 2 -I n p u t A N D G a te Physical Dimensions inches (millimeters) Order Number MM54HC08J or MM74HC08J NS Package J14A Order Number MM74HC08N NS Package N14A LIFE SUPPORT POLICY NATIONAL’S PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN LIFE SUPPORT DEVICES OR SYSTEMS WITHOUT THE EXPRESS WRITTEN APPROVAL OF THE PRESIDENT OF NATIONAL SEMICONDUCTOR CORPORATION.
