TC74VHCT138AFN中文资料东芝数据手册PDF规格书

The TC74VHCT138 is an advanced high speed CMOS 3-to-8 LINE DECODER fabricatedwith silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation.

特性 Features

• High speed: tpd =7.6 ns (typ.) at VCC =5 V

• Low power dissipation: ICC =4 μA (max) at Ta =25°C

• Compatible with TTL outputs: VIL =0.8 V (max) VIH =2.0 V (min)

• Power down protection is provided on all inputs and outputs

• Balanced propagation delays: tpLH∼=− tpHL

• Pin and function compatible with the 74 series (74AC/HC/F/ALS/LS etc.) 138 type.
