MICROCIRCUIT DATA SHEET Original Creation Date: 10/18/95 Last Update Date: 05/19/97 Last Major Revision Date: 04/02/97 MNMM54C161-X REV 1A0 BINARY COUNTER WITH ASYNCHRONOUS CLEAR General Description These (synchronous presettable up) counters are monolithic complementary MOS (CMOS) integrated circuits constructed with N- and P-channel enhancement mode transistors. They feature an internal carry lookahead for fast counting schemes and for cascading packages without additional gating. A low level at the load input disables counting and causes the outputs to agree with the data input after the next positive clock edge. The clear function for the C161 is asynchronous and a low level at the clear inputs sets all four outputs low regardless of the state of the clock. Counting is enabled when both count enable inputs are high. Input T is fed forward to also enable the carry out. The carry output is a positive pulse with a duration approximately equal to the positive portion of QA and can be used to enable successive cascaded stages. Logic transitions at the enable P or T inputs can occur when the clock is high or low.

Except for "Operating Temperature Range" they are not meant to imply that the devices should be operated at these limits. The table of "Electrical Characteristics" provides conditions for actual device operation. 3 MICROCIRCUIT DATA SHEET MNMM54C161-X REV 1A0 Electrical Characteristics DC PARAMETERS: CMOS TO CMOS: SYMBOL Vih Vil Voh Vol Iih Iil Icc PARAMETER Logical "1" Input Voltage Logical "0" Input Voltage Logical "1" Output Voltage Logical "0" Output Voltage Logical "1" Input Current Logical "0" Input Current Quiescent Device Current CONDITIONS NOTES PINNAME MIN MAX UNIT SUBGROUPS Vcc = 5V 1 3.5 V 1, 2, 3 Vcc = 10V 1 8 V 1, 2, 3 Vcc = 5V 1 1.5 V 1, 2, 3 Vcc = 10V 1 2 V 1, 2, 3 Vcc = 5V, Iout = -10uA, Vih = 3.5V, Vil = 1.5V 4.5 V 1, 2, 3 Vcc = 10V, Iout = -10uA, Vih = 8V, Vil = 2V 9 V 1, 2, 3 Vcc = 5V, Iout = 10uA, Vih = 3.5V, Vil = 1.5V 0.5 V 1, 2, 3 Vcc = 10V, Iout = 10uA, Vih = 8V, Vil = 2V 1 V 1, 2, 3 Vcc = 15V, Vin = 15V 0.15 uA 1, 3 1 uA 2 -0.15 uA 1, 3 -1 uA 2 10 uA 1, 3 300 uA 2 V 1, 2, 3 Vcc = 15V, Vin = 0V Vcc = 15V DC PARAMETERS: CMOS TO LPTTL: Vih Logical "1" Input Voltage Vcc = 4.5V 1 Vil Logical "0" Input Voltage Vcc = 4.5V 1 0.8 V 1, 2 1 0.5 V 3 V 1, 2, 3 V 1, 2, 3 Voh Logical "1" Output Voltage Vcc = 4.5V, Iout = -360uA, Vih = 3V, Vil = 0.8V Vol Logical "0" Output Voltage Vcc = 4.5V, Iout = 360uA, Vih = 3V, Vil = 0.8V 4 3 2.4 0.4 MICROCIRCUIT DATA SHEET MNMM54C161-X REV 1A0 Electrical Characteristics DC PARAMETERS: OUTPUT DRIVE: SYMBOL Isource Isink PARAMETER Output Source Current Output Sink Current CONDITIONS NOTES PINNAME MIN MAX UNIT SUBGROUPS Vcc = 5V, Vout = 0, Vin = 0 -1.75 mA 1 Vcc = 10V, Vout = 0, Vin = 0 -8 mA 1 Vcc = 5V, Vout = 5V, Vin = 5V 1.75 mA 1 Vcc = 10V, Vout = 10V, Vin = 10V 8 mA 1 AC PARAMETERS: PROPAGATION DELAY TIME: (The following conditions apply to all the following parameters, unless otherwise specified.)
