AT TA = 25 °C COMPATIBLE WITH TTL OUTPUTS VIH = 2V (MIN.) VIL = 0.8V (MAX) OUTPUT DRIVE CAPABILITY 10 LSTTL LOADS SYMMETRICAL OUTPUT IMPEDANCE |IOH| = IOL = 4 mA (MIN.) BALANCED PROPAGATION DELAYS tPLH = tPHL PIN AND FUNCTION COMPATIBLE WITH 54/74LS139 DESCRIPTION The M54/74HCT139 is a high speed CMOS DUAL TWO LINE TO FOUR LINE DECODER/DEMULTIPLEXER fabricated in silicon gate C2MOS technology. It has the same high speed performance of LSTTL combined with true CMOS low power consumption. The active low enable input can be used for gating or as a data input for demultiplexing applications. While the enable input is held high, all four outputs are high independently of the other inputs. All inputs are equipped with protection circuits against static discharge and transient excess volt-age.This integrated circuit has input and output characteristics that are fully compatible with 54/74 LSTTL logic families. M54/74HCT devices are designed to directly interface HSC2MOS systems with TTL and NMOS components. They are also plug in replacements for B1R (Plastic Package) F1R (Ceramic Package) M1R (Micro Package) C1R (Chip Carrier) ORDER CODES : M54HCT139F1R M74HCT139M1R M74HCT139B1R M74HCT139C1R PIN CONNECTIONS (top view) INPUT AND OUTPUT EQUIVALENT CIRCUIT NC = No Internal Connection February 1993 1/9 M54/M74HCT139 TRUTH TABLE INPUTS ENABLE SELECT G B A H X X L L L L L H L H L L H H IEC LOGIC SYMBOLS OUTPUTS Y0 Y1 Y2 Y3 SELECTED OUTPUT H L H H H H H L H H H H H L H H H H H L NONE Y0 Y1 Y2 Y3 PIN DESCRIPTION PIN No 1, 15 2, 3 4, 5, 6, 7 12, 11, 10, 9 14, 13 8 16 SYMBOL 1G, 2G 1A, 1B 1Y0 to 1Y3 2Y0 to 2Y3 2A, 2B GND VCC NAME AND FUNCTION Enable Inputs Address Inputs Outputs Outputs Address Inputs Ground (0V) Positive Supply Voltage SCHEMATIC CIRCUIT ABSOLUTE MAXIMUM RATINGS Symbol ICC Value Unit VCC VI Supply Voltage DC Input Voltage Parameter -0.5 to +7 -0.5 to VCC + 0.5 V V VO DC Output Voltage -0.5 to VCC + 0.5 V IIK DC Input Diode Current ± 20 mA IOK DC Output Diode Current ± 20 mA IO or IGND DC Output Source Sink Current Per Output Pin DC VCC or Ground Current ± 25 ± 50 mA mA PD Power Dissipation 500 (*) mW Tstg TL Storage Temperature Lead Temperature (10 sec) -65 to +150 300 o o C C Absolute Maximum Ratings are those values beyond which damage to the device may occur.
