It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. Pin configuration and function are the same as the TC74VHC04 but the inputs have hysteresis and with its schmitt trigger function, the TC74VHC14 can be used as a line receivers which will receive slow input signals. 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 voltages. Features • High speed: tpd = 5.5 ns (typ.) at VCC = 5 V • Low power dissipation: ICC = 2 μA (max) at Ta = 25°C • Power down protection is provided on all inputs. • Balanced propagation delays: tpLH −∼ tpHL • Wide operating voltage range: VCC (opr) = 2 V to 5.5 V • Low noise: VOLP = 0.8 V (max) • Pin and function compatible with 74ALS14 描述与应用| 十六进制施密特变频;TC74VHC14是一种先进的高速CMOS施密特 逆变器制造与硅栅C2MOS技术。 它实现了高速操作类似等效 双极肖特基TTL同时保持了低功耗CMOS 耗散。 管脚配置和功能是一样的 TC74VHC04但投入有滞后和其施密特 线接收器的触发函数中，可以用作TC74VHC14 将接收缓慢的输入信号。 输入保护电路确保0到5.5 V可 没有考虑到电源电压施加到输入引脚。 该装置可用于接口5 V3 V系统和两个 如电池供电系统备份。该电路防止 由于设备破坏不匹配的电源和输入电压。 特点 •高速：TPD =5.5纳秒（典型值），VCC= 5 V •低功耗：ICC= 2μA（最大值）在大= 25°C •掉电保护是对所有投入。 •平衡传输时延：TPLH - TPHL •宽工作电压范围：VCC（OPR）= 2 V至5.5 V •低噪声：VOLP=0.8 V（最大值） •引脚和功能兼容74ALS14
