TC74HC4514AP

The TC74HC4514AP is a kind of high speed CMOS 4-line to 16-line decoder with lactched inputs fabricated with silicon gate C2MOS technology. The device achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. The data applied to the data inputs are transferred to the outputs of latches when the strobe input is held high. When the strobe input is taken low, the data is retained at the output of the latches. All input are equipped with protection circuits against static discharger or transient excess voltage.

There are some TC74HC4514AP features as follows: (1)high speed: tpd=18 ns typ at VCC=5 V; (2)low power dissipation: ICC=4A max at Ta=25; (3)high noise immunity: VNIH=VNIL=28% VCC min; (4)output drive capability: 10 LSTTL loads; (5)symmetrical output impedance: |IOH|=IOL=4 mA min; (6)balanced propagation delays: tpLHtpHL ; (7)wide operating voltage range: VCC(opr)=2 to 6 V; (8)pin and function compatible with 4514B.

The following is about the absolute maximum ratings of TC74HC4514AP: (1)supply voltage range, VCC: -0.5 to 7 V; (2)DC input voltage, VIN: -0.5 to VCC+0.5 V; (3)DC output voltage, VIN: -0.5 to VCC+0.5 V; (4)input diode current, IIK: ±20 mA; (5)output diode current, IOK: ±20 mA; (6)DC output current, IOUT: ±25 mA ; (7)DC VCC/ground current, ICC: ±50 mA; (8)power dissipation, PD: 500 (DIP) mW; (9)storage temperature, Tstg: -65 to 150. Then is about the recommended operating conditions: (1)supply voltage, VCC: 2 to 6 V; (2)input voltage, VIN: 0 to VCC V; (3)output voltage, VOUT: 0 to VCC V; (4)operating temperature, Topr: -40 to 85.
