SN74LS75N Datasheet PDF – 4-Bit Bistable Latche – TI

Part Number : SN74LS75N

Function : 4-BIT BISTABLE LATCHE

Package : DIP 16 Pin Type

Manufacturers : Texas Instruments

Pinouts :

SN74LS75N datasheet

 

Description :

These latches are ideally suited for use as temporary storage for binary information between processing units and input/output or indicator units. Information present at a data (D) input is transferred to the Q output when the enable (C) is high and the Q output will follow the data input as long as the enable remains high. These circuits are completely compatible with all popular TTL families. All inputs are diode-clamped to minimize transmission-line effects and simplify system design.

74LS190 Datasheet – Synchronous 4-Bit Binary Counter

Part Number : 74LS190

Function : Synchronous 4-Bit Binary Counters

Package : DIP 16 Pin

Manufacturers : Motorola => Freescale

Pinouts :

74LS190 datasheet

 

Description :

The SN54/74LS190 is a synchronous UP/DOWN BCD Decade (8421) Counter and the SN54/74LS191 is a synchronous UP/DOWN Modulo-16 Binary Counter. State changes of the counters are synchronous with the LOW-to-HIGH transition of the Clock Pulse input. An asynchronous Parallel Load (PL) input overrides counting and loads the data present on the Pn inputs into the flip-flops, which makes it possible to use the circuits as programmable counters. A Count Enable (CE) input serves as the carry /borrow input in multi-stage counters. An Up/Down Count Control (U/D) input determines whether a circuit counts up or down. A Terminal Count (TC) output and a Ripple Clock (RC) output provide overflow/underflow indication and make possible a variety of methods for generating carry/borrow signals in multistage counter applications
