Overview

MC74HC4538A のピンアウトは MC14538B と同等です。入力は標準 CMOS 出力に準拠、プルアップ抵抗器があれば LSTTL 出力に準拠します。このデュアル単安定マルチバイブレータは、入力パルスのポジティブ・エッジまたはネガティブ・エッジのいずれかによってトリガされ、幅広いパルス幅にわたって高精度の出力パルスを生成します。デバイスにはトリガ入力が調整されているため、トリガ入力の立ち上がり時間と立ち下がり時間の制限はありません。出力パルス幅は、外部タイミング・コンポーネント Rx および Cx によって決まります。このデバイスには、出力パルス回路の状態に関係なく、Q 出力をローに、Qbar 出力をハイに強制するリセット機能があります。

  • Unlimited Rise and Fall Times Allowed on the Trigger Inputs
  • Output Pulse is Independent of the Trigger Pulse Width
  • +/- 10% Guaranteed Pulse Width Variation from Part to Part (Using the Same Test Jig)
  • Output Drive Capability: 10 LSTTL Loads
  • Outputs Directly Interface to CMOS, NMOS and TTL
  • Operating Voltage Range: 3.0 to 6.0 V
  • Low Input Current: 1.0 mA
  • High Noise Immunity Characteristic of CMOS Devices
  • In Compliance with the Requirements Defined by JEDEC Standard No. 7A
  • Chip Complexity: 145 FETs or 36 Equivalent Gates
  • Pb-Free Packages are Available*
