MC74ACT161DG
Counter, Presettable Binary, Synchronous, 74ACT, 125 MHz, Max Count 15, 4.5 V to 5.5 V, 16 Pins, SOIC
Avnet Manufacturer Part #:
MC74ACT161DG
RoHS 10 Compliant
NCNR
Obsolete
The MC74AC161/74ACT161 and MC74AC163/74ACT163 are high-speedsynchronous modulo-16 binary counters. They are synchronously presettable forapplication in programmable dividers and have two types of Count Enable inputsplus a Terminal Count output for versatility in forming synchronous multistagecounters. The MC74AC161/74ACT161 has an asynchronous Master Reset inputthat overrides all other inputs and forces the outputs LOW. The MC74AC163/ 74ACT163 has a Synchronous Reset input that overrides counting and parallelloading and allows the outputs to be simultaneously reset on the rising edge ofthe clock.
Key Features
- Synchronous Counting and Loading
- High-Speed Synchronous Expansion
- Typical Count Rate of 125 MHz
- Outputs Source/Sink 24 mA
- ACT161 and ACT163 Have TTL Compatible Inputs
- These devices are available in Pb-free package(s).
