Original IC Electronic Components 74HC585D Dual AND OR Gate CMOS Device
74HC58 Dual AND-OR gate
FEATURES
• Output capability: standard
• ICC category: SSI
GENERAL DESCRIPTION
The 74HC58 is a high-speed Si-gate CMOS device and is pin compatible with low power Schottky TTL (LSTTL). It is specified in compliance with JEDEC standard no. 7A.
The “58” provides two sections of AND-OR gates. One section contains a 2-wide, 3-input (1A to 1F) AND-OR gate and the second section contains a 2-wide, 2-input (2A to 2D) AND-OR gate.
QUICK REFERENCE DATA
SYMBOL | PARAMETER | CONDITIONS | TYPICAL HC | UNIT |
tPHL/ tPLH | propagation delay 1n to 1Y 2n to 2Y | CL = 15 pF; VCC = 5 V | 11 9 | ns ns |
CI | input capacitance | 3.5 | pF | |
CPD | power dissipation capacitance per gate | notes 1 and 2 | 18 | pF |
Notes
1. CPD is used to determine the dynamic power dissipation (PD in µW): PD = CPD × VCC2 × fi + ∑ (CL × VCC2 × fo) where: fi = input frequency in MHz fo = output frequency in MHz CL = output load capacitance in pF VCC = supply voltage in V ∑ (CL × VCC2 × fo) = sum of outputs
2. For HC the condition is VI = GND to VCC
