MM74HC540 • MM74HC541 Inverting Octal 3-STATE Buffer • Octal 3-STATE Buffer September 1983 Revised May 2005 MM74HC540 • MM74HC541 Inverting Octal 3-STATE Buffer • Octal 3-STATE Buffer General Description The MM74HC540 and MM74HC541 3-STATE buffers utilize advanced silicon-gate CMOS technology. They possess high drive current outputs which enable high speed operation even when driving large bus capacitances. These circuits achieve speeds comparable to low power Schottky devices, while retaining the advantage of CMOS circuitry, i.e., high noise immunity, and low power consumption. Both devices have a fanout of 15 LS-TTL equivalent inputs. The MM74HC540 is an inverting buffer and the MM74HC541 is a non-inverting buffer. The 3-STATE control gate operates as a two-input NOR such that if either G1 or G2 are HIGH, all eight outputs are in the high-impedance state. In order to enhance PC board layout, the MM74HC540 and MM74HC541 offers a pinout having inputs and outputs on opposite sides of the package. All inputs are protected from damage due to static discharge by diodes to VCC and ground.

Thus the 4.5V values should be used when designing with this supply. Worst case VIH and VIL occur at VCC 5.5V 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. www.fairchildsemi.com 2 MM74HC540 • MM74HC541 AC Electrical Characteristics VCC 5V, TA 25qC, tr tf 6 ns Parameter Conditions CL CL RL CL RL CL 45 pF 45 pF 1 k: 45 pF 1 k: 5 pF 15 25 ns Typ 12 14 17 Guaranteed Limit 18 20 28 Units ns ns ns Symbol tPHL, tPLH tPHL, tPLH tPZH, tPZL tPHZ, tPLZ Maximum Propagation Delay (540) Maximum Propagation Delay (541) Maximum Output Enable Time Maximum Output Disable Time AC Electrical Characteristics VCC 2.0V to 6.0V, CL 50 pF, tr tf 6 ns (unless otherwise specified) Conditions CL CL CL CL CL CL 50 pF 150 pF 50 pF 150 pF 50 pF 150 pF 50 pF 150 pF 50 pF 150 pF 50 pF 150 pF 1 k: 50 pF 150 pF 50 pF 150 pF 50 pF 150 pF 1 k: 50 pF 50 pF 2.0V 2.0V 4.5V 4.5V 6.0V 6.0V 2.0V 4.5V 6.0V 2.0V 4.5V 6.0V 75 100 15 30 13 17 75 15 13 25 7 6 10 50 5 15 10 20 10 20 10 20 150 200 30 40 26 34 150 30 26 60 12 10 189 252 38 50 32 43 189 38 32 75 15 13 224 298 45 60 38 51 224 45 38 90 18 15 ns ns ns ns ns ns ns ns ns ns ns ns pF pF pF pF VCC 2.0V 2.0V 4.5V 4.5V 6.0V 6.0V 2.0V 2.0V 4.5V 4.5V 6.0V 6.0V TA Typ 55 83 12 22 11 18 58 83 14 17 11 14 100 150 20 30 17 26 115 165 23 33 20 28 2 5 qC TA Symbol Parameter 40 to 85qC TA 55 to 125qC Guaranteed Limits 126 190 25 38 21 32 145 208 29 42 25 35 149 224 30 45 25 38 171 246 34 49 29 42 Units ns ns ns ns ns ns ns ns ns ns ns ns tPHL, tPLH Maximum Propagation Delay (540) tPHL, tPLH Maximum Propagation Delay (541) CL CL CL CL CL CL tPZH, tPZL Maximum Output Enable Time RL CL CL CL CL CL CL tPHZ, tPLZ Maximum Output Disable Time tTHL, tTLH Maximum Output Rise and Fall Time RL CL CL CPD CIN COUT Power Dissipation Capacitance (Note 5) Maximum Input Capacitance Maximum Output Capacitance G G VIH VIL Note 5: CPD determines the no load dynamic power consumption, PD IS CPD VCC f  ICC.
