■ 제품사양

패키지 = TSSOP Logic Function = Counter Logic Family = 74VHC
장착형태 = Surface Mount Counter
타입 = Binary Number of Elements = 1
핀수 = 16 Minimum Operating Supply Voltage = 2 V Maximum Operating Supply Voltage = 5.5 V
크기 = 5.02 x 4.4 x 1mm Preset
타입 = Synchronous The 74VHC161FT and 74VHC163FT are advanced high speed CMOS SYNCHRONOUS PRESETTABLE 4 BIT BINARY COUNTERs fabricated with silicon gate C2MOS technology. They achieve the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. The CK input is active on the rising edge. Both LOAD and CLR inputs are active on low logic level. Presetting of each ICs is synchronous to the rising edge of CK. The clear function of the 74VHC163FT is synchronous to CK, while the 74VHC161FT are cleared asynchronously. Two enable inputs (ENP and ENT) and CARRY OUTPUT are provided to enable easy cascading of counters,which facilitates easy implementation of n-bit counters without using external gates. An input protection circuit ensures that 0 to 5.5 V can be applied to the input pins without regard to the supply voltage. This device can be used to interface 5 V to 3 V systems and two supply systems such as battery back up. This circuit prevents device destruction due to mismatched supply and input voltagesWide operating temperature: Topr = -40 to 125 ??High speed: Propagation delay time = 3.8 ns (typ.) at VCC = 5.0 V Low power dissipation: ICC = 2.0 μA (max) at Ta = 25 ??High noise immunity: VNIH = VNIL = 28 % VCC (min) Power-down protection is provided on all inputs. Balanced propagation delays: tPLH ??tPHL Wide operating voltage range: VCC(opr) = 2.0 to 5.5 V Low noise: V = 0.8 V (max) Pin and function compatible with 74 series (AC/HC/AHC/LV etc.) 161 or 163 type
